Upgrade

[Uncle Shags]

Core 2 duo w/DDR2 memory is NOT an upgrade. Neither is a 7200 RPM hard drive.
Intel i3 CPU is LOWEST you should even consider. 4-8 gb of LOW latency DDR3 speed ram and a 64-128gb SSD hard drive to boot
Sata 2/3 doesnt matter all that much, its about the random ACCESS and WRITE times, IOPS. Typically above 50k IOPS would be what I consider to be fast or for gaming.

I think there may be a miscommunication. The original hardware I listed is my current rig which I am thinking of upgrading from.
