Updating a GPU and possibly CPU - Page 2

So what would be a good brand to go with? And also are the ATI's as power demanding. Someone said they are more powerful, but that's not much use if it can't run on my system.

I also would like a more quite gpu if possible.

I forgot about this thread. Sorry.

The 3DCoat demo works fine on my computer here, but I cant find the voxel sculpting thing in their forums to test.

As for power consumption, Toms Hardware has tested it and there really isnt much difference. As long as you have a 550-600watt Power Supply you would have no trouble with any single card you can choose.

As for quiet that really depends on the cooler on the card. Default fans and heatsinks are never quiet, you have to go look at ones that include aftermarket sinks for that, or install an aftermarket one on your own.

These are my suggested cards for quiet operation and still running cool.

For saving some money but loosing a bit of performance go with one of these (They both perform just about the same):

ATI: http://www.newegg.com/Product/Produc...82E16814102833

Nvidia: http://www.newegg.com/Product/Produc...82E16814121309

For some more money and getting better performance (again, about the same performance):

ATI: http://www.newegg.com/Product/Produc...82E16814102825

Nvidia: http://www.newegg.com/Product/Produc...82E16814127426

I thought you said the GTX would use too much power for my system to handle?

As for cooling, my case also has a side fan that is directly over the GPU and Processor area. I assume that would help cool down the gpu?

That's the voxel alpha thread.

No, I just said it used a bit more power than the GTS250, and that combine with the fact that the 250 costs less, it would be the card to get out of the 9800GTX and GTS250.

I'm running a 4870 on a 600watt fairly average quality PSU with no troubles. Your 580watt, as long as its a decent enough brand will have no trouble with any single GPU solution.

A fan directly over the graphics card can lower its temperature slightly, but sometimes it can hinder case airflow and raise temperatures in the top side of the case (CPU, RAM, etc).

I'll try out the vorxel alpha tomorrow when I'm back on my desktop.

Nvidia recommends 35 amps on the 12v rails for the GTX 260, which means that at peak usage, with the GTX 260 and your power supply, your computer could abruptly shut off because the system is drawing more power on the 12v rails than the power supply can give.

However, Nvidia recommends only 24 amps (288w) on the 12v rails for the 9800 GTX+, so your computer would be able to run that card (and most likely any other 9 series with the possible exception of the 9800 GX2) without any stability or power concerns.

This was my concern Twilight.

AMD/ATI has power requirements for their cards on their site as well, so you can look there. The manufacturer's suggested power level has some built-in headroom to ensure that there will always be enough power to run all your components, regardless of spikes, surges, and any other power fluctuation or condition your components put on your power supply. Or in other words, even though looking at the chart TV posted may make you think any of those graphics cards can run with a 300W power supply, trying it would undoubtedly get your system shut down a few times due to surges.

edit: I just looked on AMD's site and they don't have amperage requirements, but they do have a list of supported power supplies. It looks like your power supply is supported for up to the 4870, so you should be fine.

Unless I'm looking at the wrong supply, you have 20amps on the first rail and 18 on the 2nd. The total of 38amps should work fine. But this is the only 580watt unit on their site. Hiper is pretty good. They're no PC Power & Cooling, but they're nice enough.

Also, the specs on Nvidia's site seem to be for the first generation 65nm GTX260. The newer 55nm version uses less power.

Its the R type. I don't think it would work for the GTX series though. It only has one 6 pin modular cable. And I'm not sure where in my house this wire is. If worse comes to worse and I have to gett a different power supply, what should I go with?

My current GPU is about 8" long. I might be able to get a 10" gpu in there.

With only room for a 10" GPU you're going to be kinda limited. Even the shortest, the GTS250 may not fit. What case do you have?

Vorxel sculpting seems to be working on my computer, but I'm using the non cuda version and its running through my CPU just fine.

Its not the case that's the issue, ( I could fit a 14" gpu I believe) however its the wiring, and motherboard layout that I'm worried about. I will have to take a picture sometime this week of the interior. The Powersupply is on the bottom of the case too.

Its a lian li v1200, looks sort of like a aluminum G5 mac but with wheels and no handles.

I just looked it up, thats a lot of room. If you route your cables and wires right you wouldnt have any problems. Just be kinda creative about keeping them out of the way of major components. In my computer for instance, I routed nearly all the power supply cables behind the motherboard tray.

Hopefully this illustrates the layout even better. The one that says cpu is a mistake, its really PSU. Its altered a bit. The GPU interestingly uses a 4 pin modular cable. I will order some 6 pin ones, but I have to see if its worth getting the GTX over the GTS.

As I said, the GTS250 and the 9800GTX are the exact same card. The only difference is slightly less power used by the GTS250. Since the GTS also costs less, theres no reason to buy the 9800GTX or GTX+ anymore. Heres some GTS250 reviews that say the same thing:

By GTX I mean the 260 one with 216 processors.

Oh sorry.

Now that I think about it, you dont have a 6pin GPU power connector? That might present a problem even with an adapter.

Not really. My power supply is modular, so I can remove and add different types of cables as necessary. If I can find the cable in my house or order a new one I can at least have the GTS. But I doubt I could add two gpu power cords. So I may have to get a new power supply.

Ah, you'll be fine then. Let us all know how it goes

And if you get the GTX260, be sure to tell me what I'm missing out on by going Radeon 4870

Hmmm not much of a difference between GTX 260 and GTS 250 at 1280x1024. I'm running 2x 1280x1024 17" monitors.

1280x1024 is pretty small now a days even for two monitors its not as taxing as it once was. Things start to get very CPU bound at those resolutions.
