problem is my main rig is now full of GPUs. I even modded cards so that I could fit more in. so to use GPUs id have to build a new PC anyway. so id be looking at: mobo £70, psu, £50, cpu £100, ram £120, HDD £30. case £40 and now im already at £290 before even buying a mid range GPU. so CPUs are the way to go. + they can be used for more things. like I can off load physics sims onto it and stuff.
