need advice please! Cant decide whether to upgrade my CPU+motherboard+memory (5 year old hardware), or stick with what I have and buy another GTX 980 for SLI
Current system:
CPU: i5 2500K @ 4.5Gz
Memory: 16gb DDR3-1333mhz
Motherboard: Asus P8P67 Pro
GPU: Evga GTX 980
Since I use it mainly for gaming I know that going GTX 980 SLI will make the biggest difference to performance, but I also dont want the CPU to potentially be a bottleneck. At the same time, not a big fan of SLI. My upgraded system parts would look like so (retaining the 1000W PSU, SSD drives etc):
CPU: i7 6700K @4.5ghz
Memory: 16gb DDR4-2666mhz
Motherboard: Asus Z-170 Pro Gaming
GPU: Evga GTX 980
Do I go skylake and wait for the next generation of GPU, or stick with the 5 year old sandy bridge and go SLI?
