Just pieced together a great "bang for the buck" pc for running NX. I'd looked at all the affordable ready made systems and they all lacked a decent mobo with room for expansion. After a bit of deliberation I ended up with:
CPU: Intel i5 Mobo: Gigabyte P55-UD3R Mem: 4gb ddr3 (requires ddr3) Video: Nvidia Quadra FX580 HD: WD 500gb sata 7500
Interesting to note is I bought them at Fry's minus the FX580 which you'll never see at a consumer store. Had an existing case, 500watt ps, and cd/dvd drive. Cost about $500 +tax for the new system. I thought a low price for a great spec'd system. Never plan to "game" with it but cadcam does use cache on the cpu. I've also have learned over the years that buying expensive "fast" ram is a waste of money.
Pretty fast beast for the price! I'd first looked at a Q9550 quad cpu w/12mb cache thinking I could get a better deal on the older chips but no... The i5 got great reviews for dollar for dollar cpu cost.
The beauty of this system is I still have 2 slots open for more ram and I could upgrade to the i7 down the road.
