Yeah, the 290x is a waste of time and doing some more research I see that the 290 is very good for its price, it managed to beat the GTX 780 in a few benchmarks (such as Bioshock Infinite) on its own, kills it with SLI. The drawback of the card however is that the 290 is a really loud card and can get pretty warm. Which isn't all that surprising since AMD tends to value price/performance over cooling efficiency with many of their cards (even mine is really loud). So it comes down to: How much do you care about noise level?
Not that fussed about it being too loud as it won't be at head height (direct earshot) but under a desk & my old rig wasn't that quiet either & laptop is very loud too. For £100 less I can put up with a little noise. Case is quite well ventilated & can always buy a few more fans to keep things cooler. For price that it is I could easily afford to SLI if needed at some point too.
Might be worth going for the EVGA due to lower temps as if card runs hot & PSU does too it might cause some heat issues.
