We are also talking about the 9800GTX+, which is better than an 8800GTS. A 9800GTX+ is on par with the 4850, which is considerably better than the 8800GTS.

As for the price, I don't know where you're looking, but all the etailers I check have a handful of GTX 260s for well under $300.

RFOMownage: DDR3 isn't an improvement. It's vastly overpriced for the same performance you could get from DDR2 for much cheaper.. As I stated before, current hardware can't really make use of DDR3 properly. If you want to use DDR3 so badly, wait a few months for Nehalem and X58 mobos.

First of all, lose the DDR3. With current hardware, it shows little to no improvement over DDR2 at all.

Now then, obviously, lose the 790i board as well. I would suggest picking up a mobo with a P45, X38 or X48 chipset and an HD4850 or 4870. However, if you are set in sticking with Nvidia, ignore what the other person said. The 9800GTX+ is undeniably better than the 8800GTS. It also costs about the same price as the 8800GTS, making it a far better value...

Get a 750i chipset if you decide to go with Nvidia video card(s).

Also, Carraher how do figure two 8800GT's cost significantly less than a GTX 260? GTX 260's can be purchased for under $250 currently; two 8800GT's would cost at least $240 or more...

Okay, I just ordered a new PSU yesterday, a 500W Antec Earthwatts. Thought it was a pretty decent deal for $50 and free shipping. I just want to make sure that:

A. Is this is a good power supply? and

B. Will it be enough to power my system? I don't see why it wouldn't be, but, specs are:

CPU: C2D E6300 @2.8GHz

GPU: Diamond 3870

RAM: 2GB Crucial 10th Annv. DDR2 667 (@800)

HDD: Seagate Barracuda 500GB

Thanks in advance!

Quite a bit of overkill. Of course, that all depends on your budget too.

First off, for the PSU, a Corsair 620HX or even a 650TX would do just fine. You could grab a 700TX if you just want a future-proof PSU. Any of those three are fantastic power supplies and cheaper than the one you picked.

Next, the Raptor HDD is probably overkill. If you simply must have one, just get one. Then get a Seagate Barracuda or a WD Caviar for your second HDD for storage.

Last, 780i chipset is a bit pointless. You could get a 750i for SLI and it would save you quite a bit over the 780i.

Yes. 600 wat is a lot.Horny-Dude

To be fair, watts don't matter that much. I mean, of course they matter, but the total amperage on the 12v rail(s) is more important in determining if a PSU can power a multi GPU setup.

With that said, yes paraskhos, your PSU is perfectly fine to do an 8800GT SLI setup. As for upgrading, 8800GT is still a very good card, and with prices of them at an all-time low, grabbing another for SLI would be a great idea.
