Hell the Radeon HD 7870 would be a big step up and is only 129.99 (Newegg black friday deal), and i wouldnt say you need much more. Now if youre dying to spend that 200-250 the r9 270X would be about right...but its hardly an upgrade to the 7870. Next big step up would be like a 7970 or a 280X (both over 300$). In short, just get the 7870, i paid 189.99 (ASUS Radeon HD 7870 GHz DC2), and not even a week later i see MSI is like 160/130 after rebate!
plus you can overclock the 7870 ghz to get a little more juice out of it. depending on your full build you could squeeze up to 10 frames[/quotemsg]
I was also looking at a MSI GTX 760 Twin Frozr for $250 after MIR. What are your thoughts?
