Which GPU Should I get?

[Makol]

So my friend gave me some parts from his old build which include the following; MSI NF750-G55, AMD Phenom II X4 955, and CORSAIR XMS3 4GB 1600MHz. I have a spare case and psu to used them with, a Lexa S and a BFG Tech GS-550 550watt power supply. All I need is a graphics card for it all. I'd say $180 USD would be the maximum I'm willing to spend on the graphics card. I'd be ordering it off of Newegg. Right now I'm stuck between a GTX 460 and the HD 6850. Any input is welcome. Right now I'm leaning towards a Nvidia option since the motherboard is SLI compatible but I'm open to anything.

If you need to know the spare monitor I'll be using for it has a max resolution of 1600x900 and I think the most demanding games it'll be used for are GTA 4, Bad Company 2, and Battlefield 3 once it's out.

Might be able to pick up a 6870 for that price

I've got a Phenom X4 955 myself and 4gb Ram.

I'm running a Sapphire HD 6850, if you can pick one of those up, then go for it.

They overclock really well, I've gone from 775/1000 to 890/1160. I had the core running at 920 stable in everything, until I started playing Witcher 2.... Bumping it down to 890 seemed to fix the problem though.

I have no trouble playing any of my games at 1920x1080 on medium-high settings!
