Well I just installed a 4890, was hoping to get a GTX 295 or 4870x2 but they didn't have any so I got a 1GB from Sapphire (Fagphire). It barely fits my case LOL. I had to move my SATA cables because if I layed my 4890 down they'd probably get knocked out of the port. I have like half an inch of room left. Good thing I calculated and measured my case. If anybody is wondering, this card is beast for 200 bucks. Though most of the GTX 200 series can knock it out, it's great for its price and I wouldn't mind doing crossfire with it when I get a bigger case. I get about 60-80fps average on COD4 with 1600x1200 resolution and about 100 fps average 1600x1200 on CSS. I'm checking out Crysis now. It overclocks great and the box came with free converters (of course) and a Crossfire bridge.
