Hi Guys,

I've been out of the PC game for a while but i now want to upgrade to a 1440p monitor from 1080p. Naturally this means that I'll have to upgrade to still play on High/Ultra from my now dated XFX HD7870. As I said i haven't been keeping up with reviews and new releases etc but am back now. I don't want to spend a huge amount (Around £250) and this brings me to which is best out of the R9 280X 4GB or the R9 390 8GB. (A monitor suggestion for under £200 [1440p and around 25-27inch] would also be appreciated). My Processor is a i7-3770k which still has the potential to overclock so is going just fine.

Hoping for some quick help,
Cheers,

Ben
