Restarting - Upgrade PC or New?

[Sturmy]

Apologies for the horrid ebay page link, but any thoughts on these systems:

(£80 less for a 2500k, and £130 less for 8gb ram)

Main thing I'm not sure on is the graphics cards. Especially seeing it's only 1 dvi out.
And lack of SSD, but guess I could stick one in.

*Edit - or http://www.ebuyer.com/product/264503 but same problems in terms of lack of SSD etc

Or think it's better just to go down the build it yourself?

Just can't decide best way to go :P And don't really want to rush into one, then realise it's not suitable lol

Thanks
