Here is what you will need to consider:
If your going Dual GPU both cpu are good. But you will save a HECK (200$) more going Phenom 955.
If you do anything else (as in encoding/zipping (most of wat gamers never do lol.)) then go i7.
Now value talking:
The best build you can get is the phenom II 955. You will save a 200$ that you will be able to spend on a better GPU.
Seriously, I think very few people will recommend a GTX 295. Your even better with a HD4870 X2. It has lots of issues as in GTX260 in crossfire scales WAY better on crysis and things like that....
I say your better going with the follow
Phenom II 955
Asus Crosshair III formula
HD 5850 (it will probably be the same price of the GTX 295 ur getting on rebate since that card costs...way too much)
And with that 200~250 $ your saving, you can buy ANOTHER HD5850 and crossfire.
Seriously, no build can beat this one at performance/price.
But yes, i7 is really the best cpu out there if you have the money. Now your better doing like what ehanger said. Save the extra money for 1-2 year. Or for your girlfriend, shed be happy
