I’d reccomend you use the new i7 processor, not Intel – Core™2 Quad Processor. It’s the newest one, best, but most expensive.

RAM: you could bulk up a bit more on RAM, maybe 4GB more for REAL good performance.

Hard Drive: Is it a single 1TB drive?? If it is, try using 2 or more HDD’s set up in RAID Stripe.

Video Card should have 1GB, but with your other parts, 896 should be all right.
