This card is rather large.
With my 7900GTX:
In an Antec 900 - slightly reconfigured for more room.
My specs: XP Pro X86 / Driver version 174.74 WHQL
E4600 @ 272x11 / 2Gb Corsair XMS pc6400 @ stock speeds / 9800GTX is at stock speeds
3Dmark06 basic version, picked up around 1200 versus the 8800 GTS 640 I traded in.
Crysis @ 1680X1050, all high with 2XAA
With no AA
I'm happy with it at this early stage, coming from the 640Mb GTS for an even swap through step up.
One thing - which I cannot quantify because I'm sure exactly what to point out, textures, objects all have a cleaner
look to them. Very happy with the visual quality even though fps are not through the roof.
