Ok so my current setup is a single MSI twin frozr 4g 290x, which I play at 1080p. Here's the question. Should I get a 295x and run them trifire and get a 4k monitor,or get another twin frozr and do 1440p at 120. If I do the 2nd option I have a space in between the cards and the case is a nzxt 820, would I need to put them on water to control temps?
