Please Critique -- Need help choosing PSU also.

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! =)

This is a Newegg Wishlist.

  1. Two options:

    If you plan on Crossfiring the 4870's later, go with the 750TX and switch to a X38/X48 mobo to take advantage of the full 16x/16x Xfire. The P45 only allows 8x/8x Xfire.

    If you do not plan on Crossfiring, go with the 550VX and think about downgrading to a cheaper P35 mobo. The 45 got poor reviews compared to the P35 in terms of its additional features.


  2. 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.
  3. ^+1. Good build. All are good quality parts. Good luck. Also for PSU look in to the PC Power & Cooling 750.
  4. 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.
  5. Ahhh so that's true. I don't know how that slipped through my fingers. Well then nevermind the downgrade comment. I stand behind the rest of my comments!
  6. I've thought about downgrading my mobo just a bit. There's a step down from the current one, but other than it being an 8-phase rather than a 16, I really can't see any other difference.

    This is the other mobo I'm considering. It's a bit less, but if it works out, I could move the dollars into other areas. Comments?
  7. If you are planning on doing Crossfire, get a X48 motherboard, like hyperjoe said. Get the higher wattage PSU.
