Title says all.

Recently bought COD Black Ops, painfully obvious my X1950 even though its the required minimum and runs the game is way too slow. Would like a nice healthy bump in performance in the game. I'm not after the best absolute possible resolution or anything, just a nice noticeable improvement would be sufficient.

Wanted to keep the cost around $200, 250 tops. Seems the 6850 is very doable in that range. There are a few 6870 offerings right at the $250 mark. However, I'm hoping to not have to buy a new PSU. So the 6850 gets marks there based off what I've come up googling. Also, the 6870 from the screen shots I've seen looks to be a long sucker, might be an issue in my case, again the 6850 is probably the safer bet.

Finally, I might seriously consider folding again if I have a new GPU that can throw up some decent results on that front.

Not opposed to Nvidia possibly, but I've always been an ATI/AMD fanboy so why I'm eyeballing the 6000 series first. Also not interested in any multiple card setups, etc... just want a single honest mid range card thats a good bang for the buck.

Any advice appreciated. Thanks in advance. Thinking I might just bite the bullet and order a 6850 soon off the egg and be done with it, but thought it might be worth waiting a day or two to see what you all had to say.

Cheers
