So long story short, I'm not to sure what to upgrade on my Rig next. The spec at the moment is; Intel Core i5 2500K @ 4.4GHZ MSI P67A-GD53 EVGA 670 Cheesecake Signature2 ASUS Xonar D2X Audio Device x8 GB of Corsair RAM I'm happy with my storage, case, monitor, keyboard etc I am wondering if I should wait for the Haswell-E processors (8 cores I think?) and just save up till then as I'd need a new CPU, Mobo and Ram? Any thoughts?
To be honest your rig is fine as it is no need to upgrade. It's got the the CPU and GPU power that you will need. Do you have a SSD?
You could always get a second GPU? Two 670s best a Titan. Otherwise if you have enough GPU power, and you don't have an SSD, it's a wise upgrade.
