1800XT(512mb) or 7900GT (256mb)

Well, since you don't mind having "only" 256MB, I would say go for the 256MB x1800xt, it's faster and cheaper than the 7900GT. Also, the cheapest 7900GT and the 512MB X1800XT have the same price, so it's a pretty simple dilemma for me.

TBH from what I've heard everyone say the x1800xt with the 512mb Ram is still faster than the 7900GT as it is = on performance terms to the 256 7800gtx which was slower than the x1800xt by a decent margin especially with the latest drivers.
It really is just down to what you can afford as well because either will give great performance! I have an x1800xt and it modded to PE no problem so thats something to consider too!
and yeah prices are pretty much the same
no brainer actually!
Id definately go for the Radeon
especially if you appreciate superier image quality

The XFX 7800GT XXX edition that I have is pretty much the same speed as the 7800GTX 512mb version. But if you are going for a bog standard 7900GT then the X1800XT will be faster and have the added advantage of the extra RAM.
Sorry i find that very hard to believe.Journey said:
Infact no, i dont believe that at all.
Even if your card has quicker ram & core than the below card, it would still be much slower on the ram than the 7800GTX 512MB & have 4 less pixel pipes.
XFX GeForce 7800GT Extreme
- Core clock 450MHz+
- 20 Pixel Pipelines
- 1050MHz+ GDDR3 Ultra Fast Memory
7800GTX 512MB
Core clock 550MHz+
- 24 Pixel Pipelines
- 512MB Ultra fast 1700MHz+ GDDR3 Ultra Fast
-----------
Yes get the cheaper & quicker X1800XT 512MB, the extra ram will be better in the long run.

At 1024x768 the 256mb does indeed outperform its 512mb counterpart. At 1280x1024 they are pretty much even, but at resolutions over that the 512mb pulls aheadnaffa said:im not certain on this, but im pretty sure the 256MB X1800XT out performs the 512MB version on resolutions 1280 and below?
as i said, im not certain but ive heard it mentioned on here before.

Why would you find that a 24pipe 7900GT at 580MHz core with mem running at 1800Mhz, has a hard time beating a 7800GTX 512MB 24 pipe which runs at 550MHz core and 1700MHz mem
EDIT: Oh I see why, cause in my original post, I mistyped 7800GT XXX, not 7900GT XXX. DOH! DOH! DOH!

At 1280x1024 with AA and AF enabled the 512mb version pulls ahead of the 256mb version due to the inscreased frame buffer size.
At 1024x768 the 256mb version is indeed faster depending on the game you play.

Go for the 512 card m8. Theres more to life than the res, like running high textures in Fear (looks much better), ultra high in quake and doom ( not that I could tell the differnce ). I think 512 will be a mimium to play games this year at high quality even at 1280x1024

The fps faster with 256mb quote came from Gibbo. He also stated however that the fps increase of the 256mb card compared to the 512mb card was only about 1-2fps under 1280x1024...for that sort of deficit, I'd rather have the card that can do high res with filtering and good fps, or high res with great fps with lower filtering.
well I just got my 7900 GT and ran some benchies.
Running it at 550/1624 and got the same score as someone in this forum with a 512 MB x1800 xt overclocked to 690/1600
same 3d mark score for 50 quid cheaper
I'm 120 points off breaking 10k in 3d mark 05.
And there is still some more headroom in the clock.
these 7900 gts are nippy cards

Doesn't Doom3 need 512Mb video ram to run at 800x600 in the highest quality mode?
If you want the highest quality you need 512Mb regardless of the res u play on.
Please correct me if I'm wrong as I'll be buying a new Gfx card in the next fortnight!

I can clarify that. It has been tested and at lower/mid res a 256mb card can~ outperform a 512mb card.

As I posted above, regardless of res you need 512 for textures in some games. This is only going to become more comen
