I figured its about time I got myself a christmas present and I'm looking into building a new pc, my budget isn't great (looking to spend no more than £600) and 20% VAT doesn't help either in the UK.
I came up with imgur com/0Bg2h.jpg for £560 but since I'm not really that clued up is there any other options I could get in my sort of budget?
Well you don't need a sound card. Your CPU choice is kinda outdated. PSU is decent at best. Wrong RAM and 1x4 isn't really optimal. Case is more a personal preference but I'm not a fan of that one and no front USB 3.0 (perhaps not a big deal to you), still not a bad choice if you like it though.
Either is fine even though 7770 is kinda on the low end for a GPU. I'd try and get a 7850 or 650ti at least but again what you have will work.
second build has a 3570, if you could spend a little extra you can get the 3570k which is fully unlocked (for overclocking,) which is worth it in the long run. You need a Z77 instead then as well instead of the H77.
