Hi there! I just recently got a EVGA 780ti SC and am not sure If I made a mistake or not. It cost me 700 some dollars. I could have gotten the XFX 290 non X DD black edition aftermarket cooler for 470 dollars instead. I only have one of those 144hz asus monitors without g sync. Most of my games are last gen and so I just want at least 60fps so I can use my 144hz monitor some. I also play bf4. Do I need 780ti for 300+ dollars more or should I return it and get the 290? I have an MATX case from Cooler Master, the n200 with 2 intake and 2 exhaust fans. I hear the 290 is a bit hot. Would it be fine in a MATX? Also, the 290 has a lifetime warrenty and 4gb vram and the 780ti has 3 gb vram. What should I do? Thanks.
