I’m having quite a difficult time trying to choose the most optimal graphic card(s) for a 4K gaming PC that I am in the process of building. I want to be able to game at 4K resolution on high/ultra settings and maintain 60+ FPS as much as possible. I’m willing to spend up to $1,000 on graphic cards, but I also want a solution that is truly going to be the best bang for my buck.
So far, I’m considering three options (but I am certainly open to other suggestions!) for graphics:
1) One AMD R9 295x2 (automatically crossfire) (cost: ~$750)
2) Two AMD R9 390x’s (crossfire) (cost: ~$880)
3) Two Nvidia GTX 980’s (SLI) (cost: ~$1,000)
My first question is, is there even any difference between one 295x2 and two 390x’s? My understanding is that the 390x is just a rehash of the 290x with more memory, and the 295x2 is two 290x’s on one card. Would two 390x’s in crossfire outperform the 295x2, or would the performance be about the same? If there is no performance gain, I would prefer the 295x2 for two reasons 1) its cheaper and 2) it already comes with a radiator, fan, and a closed-loop liquid cooling solution, whereas the 390x does not.
And this brings me to my next question. Is it true that, in general, an AMD card will run much hotter and use a lot more power than its equivalent Nvidia counterpart? If I did end up going with two 390x’s, would I need to purchase a separate liquid cooling solution for both of the cards to keep their temperatures at a reasonable level?
On the Nvidia side, would two 980’s in SLI be worth it? I know two 980’s in SLI are extremely powerful, but given the cost of this option compared to the two AMD options, would the cost of this solution truly be worth it? Would this solution outperform the AMD solutions? Would these two cards require the purchase of a separate liquid cooling solution to manage their temperatures?
Finally, how many watts will my power supply need to support all of these options?
Also, feel free to suggest and recommend graphic card solutions other than those I listed (but please explain why you are recommending it).
