I have do some research about 6600 GT vs X700 PRO.

3D mark said x700 pro > 6600 GT
Gaming testing said 6600 GT > x700 pro
and other testing say different thing.

NVM. THe winner is 6600 GT.

but i do have a new qs, what is the performance gain of using 2 6600 GT with SLI compare with only one 6600 GT?

check out Anandtech's article; it compares SLI setups with single card setups (e.g. 6800 vs 6600 SLI vs 6800 SLI...etc.)

Your better off just getting one 6800GT, oc it to an ultra. Get a second GT later. My single 6800GT overclocked to 440/1200 scores way above the sli 6600's.

You can pick up a 6800GT now for under 400 bucks...

u guys are right. I checked the review about Sli vs single card n there is one bad thing about sli. (i dunno if u know it yet)

Sli won't give u much performance improvement under setting at 800x600 or 1024x1000 (only 5-7% gain in performance). It shows significant improvement in performance when the setting is at 1400 or 1600 (40-50% improvement). What a waste.

I should get a single ultra instead

The performance boost from SLI all depends on how graphics dependant your test is. It wont boost say 3Dmark2001 SE scores too much because current graphics cards are already too powerful for it and it ends up being much more CPU/Memory/Chipset bound.

But if you run something like Doom3 on high quality settings, then it's mainly graphics card bound and you will get a massive boost from SLI because the graphics cards become the bottleneck for performance.

Also, the graphics cards are what expands the image out from your base resolution to something like 800 x 600 all the way up to 1600 x 1200.
The higher the resolution, the more load on the graphics card (not CPU/Memory/Mobo)

thats why sli is good at high resolutions get alot more frames per a second vs a single vid card.
