About GFX's you're not quite right. PS3 has an equivalent of 1900xtx & X-Box 360 - 7900GTX. So... I guess 7900GS will be quite good for that.
P.S. I'm not woriied - I have 8800GTS =)
ummm no it doesnt....for starters...nvidia makes the gpu for the ps3 and ati for the xbox, and neither are as powerful as you just mentioned.
PS3 = 7800GTX 512
thats pretty much the chip on which its based (g70... 6 vertex shaders, 24 pixel shaders, 16 ROPS) clocked at 550Mhz (which the desktop 7800GTX 512 edition was)
the 360 isnt much, if at alll, better mind you....its just a lil more flexible with its unified shaders and tile rendering techniques (mostly used to get "free" aa out of that 10mb edram chip.... its not big enough to fit a multisampled 720p image in...it must be chopped up or "tiled") (note unified architecture |= DX10)
id hazard a guess and say the PS3 probably has the raw power, but the 360 makes much better use of what its got given its flexibility. the xenos has full access to the 512mb of ram on the 360 as well, whereas the RSX in the ps3 has 256 actually wired to the GPU package, and if needs be can steal some from the 256mb for the cell....but at a cost.
i cant see many sony games being 1080p because of that choice to be honest. also add to that g70's pretty poor aniso filtering quality, a bugbear for all G7x users. (read shimmering textures)
another thing is, because everyones got the same hardware, and theres no bloatware OS it means devs can optimize to the moon and back which is a good part of the reason why the consoles, despite having graphics power akin middle of the road DX9 hardware, they can still produce some pretty lush looking visuals.
