Hi Guys, I'm thinking of upgrading the PC and looking into whether to:

1. Upgrade just the GPU
2. Upggrade the CPU and the GPU
3. Upgrade Other components as well as (1 or 2)

Details of my system are below;

Antec 300 case - This is a bit small and could do with an upgrade to a full tower.
Antec 1200W truepower quattro power supply - This is pretty good, but would be better if the cables were modular
Asus Rampage 4 formula - I guess this would need an upgrade if the CPU I moved didn't fit this socket, would prefer that if I upgrade the system that the mobo and Ram could stay the same.
G.skill 2400mhz ripjawsz 16g- runs well, no problems in general
Intel i7-3930k- ??

Gigabyte GF GTX 680 PCI-E 3.0 2GB 256-bit DDR5 - ??

Kingston sv200s37a - 128gb SSD (OS) -
Kingston SH103S3120G - 256gb SSD (FPS Games) -
WD20EARX-00PASB0 - 2Tb (Other Games) -

Corsair K60 - Noisy for TS, but love the feel of these keys

Rocket Kone XTD - Nice for most games

Can you offer any advice?
