Help the noob!

Hey guys, I'm not very clued up on all the technology that is involved in building your own PC. My budget is £650 for all the parts INCLUDING Windows which is about £90. I don't need any peripherals as I have them all ready and sorted. All I need is a reliable PC that is suitable for general surfing, youtube, and more importantly running WoW on high-ultra at 50-60fps, perhaps less in raids. Considering I've played on a toaster for about 5 years with 10 fps on minimum settings, I think anything will be a bonus! Are there any set ups/ parts lists that you would recommend? I've spent about 10 hours reading the internet and it's all jargon, and not really related specifically to WoW so I thought I'd come and ask here.
Hopefully my budget is realistic to achieve these requirements! Oh, and I'm based in the UK.
Thanks

This will set you straight and meets your budget. You'll get about 60 FPS in most areas in WoW, in raids you may be hanging in the high 40s when there is a lot of action. If you can cough up another £100, you can get a 970 and get 60 FPS everywhere on ultra.

I should note, the build I listed doesn't have an optical drive - who needs one in this day in age? But if you are one of those people who does need one, we'll have to switch out that case - unless you just want an external one that runs off a USB. But I did not tough my optical drive for years before I upgraded and didn't bother getting one. You have to set your USB as your boot drive when you install Windows, but it's easy.
