does this highend pc of your include the Xeons Processors and like 20 gigs of rams with a RAID 6 and Tri-SLI GTX480's?
that'd be so epic, i want a pc like that. you could try building 2 pc's inside one, if you get what i mean
That would be absolutely pointless. Anything that needs those Dual CPUs and that ram is some sort of mainframe/server/scientific calc system. In which case, it wouldn't use the 480s. Oh, and if you were gaming, you'd need both Xeons on watercooling, so you could get them to 4.5GHz-ish where they don't bottleneck the 480s. The only full-use for that would be folding, lol.
If you want a high-end build that isn't going to be too far beyond anything to be useful, go with:
X58 Mobo
i7-980X
Prolimatech Megahalems with some Noctuas
3x3 GB Corsair Dominators 1800MHz
Dual ATI 5870s in Crossfire
Corsair HX-1000W
2xGSkill 128GB SSDs in Raid0
2x1.5 TB Seagate 7200.12s in Raid1
...and OC the hell out of the CPU and GPUs.
Regardless, you really need to give us an idea of your skill level before we can suggest much.
