Hi there, I was wondering if the fine people of this forum could take a look at this wish list and critique the products for me. I'm aware that there are 2 psu's in the wish list, I'm having trouble deciding what wattage I need for the components. I'm also looking to save a little dough, so if you see anywhere where I can shave a few dollars off, I'd greatly appreciate it! =)
Either power supply is good. I have the 550W for an A64X2 system with an 8800gt which runs no problem. For the $30 difference, I'd say get the 750 just because it's cheaper to get it now than regret later, but the 550 would likely be sufficient.
As for shaving off moneys, you could find some slightly cheaper memory but it wouldn't save much more than maybe $20. You could shave off $50 or so with a cheaper motherboard. The case could also be lessened, but this is your call ultimately. I would consider upping the processor to a Q6600 since it's not that much more money.
The only thing about p35 mobos is that they don't support pci express 2.0 though. I don't really play on doing crossfire, and I only plan on overclocking the cpu to 3.6GHz so that it will run synchronously with the DDR2 800 memory.
500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)
Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products.
