Hello all, I'm an irish pc builder here looking for some advice,
As title says I'm building a 4k gaming pc and need advice on gpu choice,

In Ireland the 290x's are still cheaper then the 780tis (crypto mining isn't really a thing here). However I'm planning in putting the system on water, I've found a set of 780ti waterblocks for 100€ which is considerably cheaper then what I'd pay for the set for the 290x's so the price evens out that way!

Question is, should get the 780ti blocks and cards or pay about the same money for the 290x's?

From what I can tell, depending of the game, each of the pairs can be better or worse than the other. However the 290x has more vram, which might help on the long run. the 780ti run cooler and more efficient.
I heard nice things of the next generation GPU's, It might be worth it to wait a bit for your dream gaming computer. Also check out the 295x2 which is definetly better than 780ti sli or 290x cf
In terms of what you need ( best fps for 4k ) , it really depends on the game. look trough those articles that I provided and based on your genre of games, decide.
cheers

290x crossfire bests 780ti's in almost all situations at 4k.

at best they trade blows if you heavily over clock the ti's. note my water cooled 290x's cost me the same price as the stock ti's at the time when i bought them and run at 1150 core +50mv no problem 45C, i could squeeze more ~1175 but the extra heat pushes my 2600k above 60C which i have at 5ghz 1.41v.
