I currently have a prebuilt Asus from 2012. It has a i7-2600 and 8gb of Ram. I also put a GTX 970 in it. Basically as it is getting quite old, it has really slowed down quite a bit and I am having issues with the USB drives. I was curious as to what would be a conservative upgrade to it. Id like to buy a prebuilt PC which is large enough to fit my GTX 970. What would be a logical upgrade, barring anything crazy expensive?
It depends on how much you want to spend. You could just upgrade the cpu and gpu and that would breathe some new life into it, although I wouldn't attempt to overclock if you have hardware problems with the usb.
