I know the advice is likely to build my own, but my dad isn't too fond of this idea (and he's paying for it, it's not mine). I've been looking round at prebuilt PCs, and this rig seems decent enough. I'd like to know your opinions on it:

Upgraded with an NVIDIA Geforce GTS450 1GB graphics card, and a 500W power supply.

Altogether it comes to about ￡530, and should be capable of running Skyrim pretty well (that's my main benchmark).

If you understand intercourse, you can build a computer. Just stick the point in the hole abut 80 times and screw the heatsink and video card in.

If prebuilt is the absolute only option, I'd recommend buyXG, and I'd also recommend you pick a PSU above 600W.

Also, from personal experience, the GTS 250 is a really good budget card, and the GTX 460 is the best card I've ever gamed with, especially when comparing price to performance.

Take note, though, that I really have no idea what I'm talking about. ^_^
