See where that puts you. If you still want more performance, get the 7850 and sell your old GTX 470 on eBay. The total cost to you should be around $150.
Yeah, I was hoping to spring for a hd 7850 2ghz cause I know that would make a huge difference. Money is an issue at the moment. I'll just save and wait. I was thinking of buying a nice CPU cooler and O.C'ing the i7.
Honestly, I would only get the 2GB version if i had a monitor with more than 1080p resolution, but anyway the 7850 seems like a good choice for that budget.
