hey everyone So I'm new to upgrading my hardware but I though it was about time I give it ago as I like to get as much from my pc as I can. I make games for a living and sometimes have to render out animations and videos via 3d software packages (im not sure if this info helps but what ever ). I am currently running GPU: Geforce GTX660 Ti CPU: Intel Core i53570K CPU @ 3.40GHz Memory: 16GB RAM (not sure which) Windows 8.1 Power plant 850w (I think) mother bored Asus P8Z77-v X2 500g Hard drive not sure which I think WD with as many screens as I can possibly get to work on it (only two for now would like more though) oh and i have £100 - £300 ish to spend what should I get ???
