Take your own advice...the only reason Dell is cheaper is BECAUSE THEY GIMP THE FUCK OUT OF THEIR PARTS. :P Multiboxing won't allow such thievery of vital system parts, pay a little more to a reliable brand of parts and be assured yer shit's full-powered and gonna last through future upgrades.

If you can afford the upgrade, go for it, might run alot better and more performance, especially in towns for showing off, is good :P
