Need help deciding on a videocard

[Kenkennings]

Im looking to buy a new video card and i dont want to spend more than $150 right now because i plan on buying another one around tax time to crossfire them. I know I have to buy a ATI card because im building an AMD system so i need some help choosing a nice ATI card to run games like Black Ops and battlefield Bad Company 2. I like this one Newegg.com - SAPPHIRE Vapor-X 100284VXL Radeon HD 5750 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity and its $120 right now. Would these be worth crossfiring? Would one of these run Black Ops for now until tax time then i will buy another one.

if you're adamant on going xfire and amd.....

Newegg.com - ASUS CuCore Series EAH5770 CuCore/2DI/1GD5 Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card

2 5770 ~= 5870...

if you cant stretch 30 extra bucks you'd be better off w/ 6850 in the long run..

Newegg.com - GIGABYTE GV-R685D5-1GD Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity
