might be struggling with the budget your on the best i can do is

AMD Phenom II Dual-Core 3.10Ghz clock speed (AM3 Socket) £60
Asus M4A78LT-M LE AMD 760G (Socket AM3) PCI-Express DDR3 Motherboard £55
Corsair XMS2 DHX 2GB (2x1GB) DDR2 PC2-6400C4 TwinX Dual Channel - £30
XFX ATI Radeon HD 4350 1024MB DDR2 PCI-Express Graphics Card - £40

on that sort of budget it really is the lower end of the spec and wouldn't really be handling many of the latest games that well, i would deffo consider waiting abit and saving abit more or selling what you have now and buying something prebuilt as something like your link or what ive specced isn't that great and will soon be out of date
