The Abit NF7S nFORCE 2 Mobo is one of the best quality available. It has onboard Gforce4 Vga, 5.1 surround sound, usb 2.0, firewire, and everything else you could need.
I realize that at just under £100, it's not the cheapest available, but it should keep you in good terms with your P.C. for years to come.
P.S. If you want to upgrade the VGA for some seriously heavy gaming, you just need to add one of the top range GFX cards.
