Im building my computer this weekend and I'm at last second changes. Part of its uses is for high end gaming and I want to play battlefield 3 and all the highend games coming out. That being said I bought the gtx 660 graphics card when buying my parts and it was on sale for 30 dollars cheaper (230$) and im now looking into the gtx 660 ti which is on sale for 120$ (300$). Would it be worth the extra 70 dollars to upgrade this part? Thanks to anyone that helps!
