I'm wanting to play the latest games, Crysis, Call of Duty etc and because of this had to build a new gaming rig, because the old AGP based computer didn't have the graphic card support, and I didn't think it was worth the investment in a later AGP graphics card.
So I have an
Intel Core 2 Duo E6700 2.66GHz
Intel DQ965GF motherboard
8GB OCZ RAM
Windows Vista 64-bit Ultimate Edition
500GB SATA Seagate 7200rpm, 16MB cache drive
I've currently got a Nvidia Quadro FX5500 PCI, which I need to replace with on of these
The 8800GTS 512 is definetly the one you want.
And forget about the cards you saw with 1 gig of memory.
Over 512 meg with a 256bit wide memory buss does NOTHING for you performance wise.
That is why the old king of GPU's, the 8800GTX has a 384 bit wide memory buss to go with it's 768 meg of memory, and still kicks every other cards butt at high res with AA enable. To utilize the extra memory without a bottleneck, you need a wider memory buss.
The 1 gig cards are simply a marketing ploy to entice people into thinking more memory is better, without researching what the card's other specifications need to be in order to make more memory actually useful.
same here the 8800gts 512 is better and newer. If you have an extra few bucks spring for the 9800gtx since there dropping to $199 but not sure what that translates into your currency. If you don't the 8800gts 512 is still a great card for most games.
