Should I crossfire or buy a new better card

[Ryarwood99]

My setup
CPU: i7 4790k
MOBO: AsRock z97 anniversary
GPU: Radeon r7 260x
PSU: TS XFX 550w
I'll need a new PSU either way but which way would be more cost effective? To buy a new MOBO with crossfire support and buy another 260x or buy a single more expensive GPU. Also what card should I get if I get a new one, what size PSU, and kind of off topic what's a good, cheap CPU cooler? Thanks in advance!

I also use a UHD monitor if that matters

That is a weak GPU, crossfiring it wouldn't suffice. We don't know your budget but based on your specs you can easily fit a top GPU in there.

Adding to RCFProd's statement, there's no need to upgrade the PSU for a single GPU. Just replace don't CF.

I would most likely like spend max $300 but preferably around $200-$250

But I actually haven't asked what kind of performance you want in games. Does it have to be high/ultra settings at 60 fps (1080p)?

You could decide between the GTX 960 2GB and R9 290 4GB.

The GTX 960 is less good but is extremely efficient whilst the R9 290 is more of a powerhouse that typically is less efficient.

I just want the best performance that hopefully doesn't force me to upgrade PSU and is still in my price range (what other types of performance are there?) Thank you for your help thus far

I would then look into a 280x.
