Upgrading from BFG 7800 GTX - Please advise.

post #1 of 7
Thread Starter 
Alright well in my system I've got an ASUS A8N-SLI Deluxe mobo, an AMD X2 4200+ processor, 2 gigs of Corsair XMS PC3200, and a BFG 7800 GTX graphics card. The graphics card is great but since I play very graphical-power-taxing games such as BF2 at a higher than standard resolution (1680 x 1050), I'm still not getting the "flawless" performance I want.

The upgrade I am considering is the ATI X1900 Crossfire such as this one here:

http://www.newegg.com/Product/Produc...82E16814102676

The card has a core clock of 625Mhz versus my card's 460Mhz. The memory clock is 1450Mhz verus my card's 1300Mhz. Finally, the onboard memory of the ATI GPU is twice the memory of the Nvidia one I have.

From a financial standpoint I could probably get $400-$450 for my used (BFG offers a lifetime warranty) BFG 7800 GTX card on eBay and would have to pay $100-$150 to be able to grab a new X1900.

Another issue is that my motherboard is built for SLI whereas the X1900 can be used in a similar setup with a different board enabled for Crossfire. If I ever wanted to do that in the future, I'd need to get a new board or stick with Nvidia cards.

The only other Nvidia step up from what I have that I have seen is the 512mb version such as the one BFG makes that has 1750mhz memory clock and 580mhz core clock.

Would I get more gaming performance (smooth FPS on HIGH resolution) from 580/1750 or from 625/1450? Also, would the step up to either of those speeds from the 460/1300 I have right now be worth $100-$150 in your opinions?

Another factor to consider is new and improved products from either ATI or Nvidia that may be coming out in the near future.

If anyone can advise me as to what they would do in this situation considering all of the above (price, performance increase, dual-card compatibility, future products), I would greatly appreciate it. Thanks!

PS: I don't think that my processor (overclocked to 2.5ghz @ 8.5 x 194) or my 2 gigs of PC3200 RAM are slowing me down that much but if you think that upgrading my graphics card will not be a huge performance increase considering my other hardware then let me know that as well.

THANK YOU.

Buy another of the same card and run in sli. check some benchmarks on google.
No sence in getting rid of a top end card for something that gives you a slight increase in performance, 15% (not worth the money.)
The 1900xtx gets 10-15FPS at 1600x1050 over the 7800 GTX 512, thats very minor IMO.
Two of your current cards will get you anywhere from 50-90% more FPS, if nothing else requires your money that would be the way to go.

two 7800 256's will out perform one 7800 512 GTX.

If you decide to wait, once the new line comes out, you would do great to give it a few months and get your sli setup of two 7800 256's running for considerably cheaper.

Yeah, if you get another GTX you'll be flying in BF2. I have 2 7800GT's and I have every in game setting at max playing at 1600x1200 and it seriously stays between 70 to 100 fps ALL THE TIME. Another GTX would be more than enough.

However, if you only want a single card for money reasons, then wait for the 7900GTX. You already have an Nvidia mobo, might as well stick with that and the 7900GTX comes out in like 2 weeks, March 9th I've been hearing. The 7900 will be pretty sweet.
