Whats the pros and cons of the 8800gts 320mb;; and the Radeon X1950PRO

The 8800 GTS 320 will eat the 1950 Pro for breakfast. Flight simulator even using two 8800 Ultra's can only do 30-40 FPS, its a very hard title to run.

The 8800gts is twice the card of the 1950pro.
You didn't list your processor though. Unless you have a fairly decent processor, anything over the 1950pro may be a waste. The flight simulator will also benefit from a very fast processor.

oh sry a amd athlon 64x2 5200 2.62x1mb l2 cache

If you can afford it get the 8800GTS. I guess. I use the 1950PRO 512mb and play everything very well. I only play w/everything maxed out in my vid card drivers and in the games too. I feel that is the only acceptable way to play a $50 game. BUT I would go DX10 if you can. I guess. There's only one question... why choose between 2 hugely different cards. If it's $ then get the 1950PRO512mb. If it's cuz you have a slow CPU then get the 1950PRO512mb. If you plan to upgrade further in the future and need something to hold you over for now... 1950PRO512mb is pretty darn good but the 1950XT is much faster.
Flight Sim 10 is heavily CPU dependent. You can play it maxed w/the 1950PRO512mb though. IF you have a good CPU.

w/that CPU you should be able to take over the world. lol

yea ddr 800 2x1mb ram ima overclock to 3.2ghz
its just that they have the close memory speed and core clock so that didnt seem to different

oh this a good enough power supply for the 8800gts

and this m/b http://www.newegg.com/Product/Product.asp?item=N82E1681...

good mobo... bad pwr. try at least 550w. the future will demand it. MORE POWER MO BETTA.

did u see it it has 33 amps thats good right

can u find one for 79.99 and over 24amps 12v

The 450w PSU will handle a 8800gtx, so it's not bad. Yes it would be better to the 550w one, but that would be about $20 more or so. I would get the 450w one, if $ is of major concern. It'll work fine for a 8800gts or even if you upgrade to 8800gtx too. If you don't want to pay for shipping and don't want to worry about the MIR, look here for $80 shipped:

or better yet (when in stock) for $11 more you could get the 520w one

If you (trust the MIR process), you could get this 550w Antec for $65 shipped after MIR:

Now that's a smokin' deal, if you get your rebate on it (which is $45!!!).

ya i got a little over-zealous.
450w will work.
night

just get a brand name psu cuz you get what you pay for... my friend has lost 2 mobos due to his cheap psu

corsair has excellent PSUs and yes it's plenty for a 8800GTS

That's kinda funny that Corsair and Mushkin are making PSU's. I have a Mushkin 550w. VERY solid and oh so pretty. The mirror finish and green light is cool. Haven't looked into Corsair yet, but I assume that they would be very good PSU's.
I stand by what I wrote earlier though. The future is gonna require more power. By the future I mean if you want to get a PSU that will be upgrade friendly... ie: 2 vid cards, more ram, more hard drives etc. you will want to get 850w or better. You see if $ is a concern then that's one thing-end of story, but if you want good clean reliable power even @450w you'll need to spend a little more. The catch is that you could spend 80$ on 450w now, but if you spend 30-50$ more "now", you'll be happy in the future. It happened to me. I wanted good power NOW, but I wish I'd have spent a little more and bought the 700w or 850w. I can't upgrade to 2 vid cards or a better CPU with just 550w. I spent $110.00 on 550w which is more than enough for what I have. BUT like I said IF I wanted to upgrade what would I do with my $110.00 550w PSU??? I could have spent an extra $30 and got a GOOD 850w PSU. I wish I would have known that Tom's forums were so helpful. I want to help where I can now. I have been building gaming rigs for 8 years now and have a good bit of knowledge and have done research... daily since 2000. I love this stuff. I was programming in basic on a Commodore 16, then Commodore 64 back in the dark ages and I know what goes into the games of today IT'S SOOOOOOOO cool. BLAH BLAH BLAH... good luck with whatever you get.

yea g but im not looking into the furture i build a new one like each yea so im uptodat with stuff

Good approach.

So does that mean that you build a complete system from the ground up, every year? If that's the case than the 450w Corsair would work just fine for what you want. The Antec one I quoted would be better, but you would have to trust the MIR process to get the best deal.

I personally like the X1950XT. Fast and cheap.
This might change when the 2nd gen DX10 cards come out in a few months.

2nd that enewmen, but it's becoming harder to find x1950xt's at a resonable price.
