Oblivion and Tomb Raider Legend are graphically great games, but they are also not very well optimized AT ALL. Especially Oblivion. Hopefully this trend won't continue.
I mean, check out Quake 4. I think it looks friggin awesome at 1600x1200 with everything fully maxxed... and it runs buttery smooth ~ 60 fps with a 7800gtx. Half-life 2 also still looks quite amazing, especially the Lost Coast with HDR.
Our 9300 will definitely be mid-high range until the end of the year. Remember that you are investing in a laptop, for mobile gaming... if you want constant top end graphics, then get a desktop, definitely easier to upgrade. Of course, if you are ebay savvy, you might be able to flip your gaming laptop, and get an new notebook for about the same cost difference as upgrading a top end desktop video card... so who knows... ok, I think I'm rambling.
