Hey guys, im looking into upgrading my system a bit in the near future and am wondering what the best upgrade route would be. I was thinking of going with an intel i5 3570k for a new processor or a GTX 660 for a GPU upgrade. Not sure if my 955 will bottleneck with it or not so im not sure if a CPU+ Mobo upgrade is necessary yet.
+1 to overclock and get the GPU, if you need PCIE 3 in the future get it then as Intel will be on a new chipset in June (ish) when Haswell releases, so buying an Intel board just for future proofing is plain stupid.
I prefer watercooling but obviously that throws budget concerns to the bin - you can't get proper water cooling for less than $100. If you have less than $100 I'd recommend air cooling. It scales well from the $30 Hyper EVO to $90-ish Noctua and other massive coolers.
