NVIDIA GeForce 7800 GTX 512: More Than Just More Memory

Day of Defeat: Source Performance
It seems that there is some sort of ~60 fps cap that we can't get around in Day of Defeat: Source. We made sure that vsync was disabled and that max_fps was set to a high value, but nothing seemed to remove the framerate limit. We tested the game with all the settings on the highest possible level but AA (which was toggled between disabled and 4x).
Without AA, cards don't really start to distinguish themselves in performance until above 1600x1200. The 7800 GTX 512 does very well under these conditions and leads just about everything including most SLI numbers (with the frame rate cap, CPU overhead of SLI starts to decrease the performance benefit).
The high end ATI hardware again scales better than NVIDIA hardware when 4xAA is enabled.

i still need to figure out what to get for my Computer so i can run CSS at native res (1680*1050)its hard having to always scale the games.

i would assume so, seeing as how it would be a very good use of the second slot. but two slot designs don't always do that.Fluppeteer - Tuesday, November 15, 2005 - link
At least one picture I've seen (Ars) shows vents in the second slot backplane. Theair seems to blow in both directions. Which is better than nothing, but I might
still have to make some kind of ducting to stop the fans at the front of my
case blowing into the open end of the shroud. This is one reason I prefer water
cooling, but I'm too wary of cooking the RAM if it's not fully cooled.
(Saving up...)

Good review, good to see some high(er) resolutions being benchmarked.Thanks for the efforts, people.
Just wondering, have any of the cards other specs changed? Is it still
one dual-link and one single link DVI (the latter run from the chip,
the former from external SiI parts)? (Since the 512MB 6800Ultra was dual
link and the Quadro FX4500 is dual dual link, I thought I'd check.) I'm
still hoping someone will get around to testing the G70's DVI quality on
the single link output for me, since the issue with the 6800.
I don't suppose nVidia took the opportunity to stick some of SiI's
HDCP-capable TMDS transmitters on it, did they? They're playing
catch-up with the X1800, and it would be a good time for them to
spend the extra few dollars on fixing it.
I'd be quite interested in some audio measurements of the fan, too.
Speaking of which, is the airflow actually useful with the Quadro
fan? I've got a lot of air blowing from the front of my case to the
back, and I've suspected that the overheating issues I've seen with
my 6800 are because the card's fan is fighting the case airflow
(for some reason nVidia's fans seem to blow the wrong way round).

So how bad does this spank my 5900XT? :Pbob661 - Tuesday, November 15, 2005 - link
I had one of those. You might be able to dig up an early benchmark on the 6600GT that will show how it compares to the 5900XT.bob661 - Tuesday, November 15, 2005 - link

Ok, if this peanut represents the 5900XT, the GTX 512 would be the size of a melon. ;)viciousvee - Monday, November 14, 2005 - link
For the price this is really for people with a "I don't care what it cost" (big) budget! Get 2 GT's (7800 ones) and call it a day. N.E ways Good article but I would like to see more benches with WOW (World of warcraft, even though they don't support SLI setup) and with 2 setups rather than one, one with the AMD 3500+ and the 57!Spoonbender - Monday, November 14, 2005 - link
You mean, get two GT's (which would cost about the same as one of these, while offering far less performance? No thanks, if I were to spend $6-700, I'd go for the faster solution. Which means this card.As for the rest, well, why is it relevant? AT is a hardware site, reviewing hardware. They're not benchmarking games to find "the best WoW card", they're benchmarking to find the best card overall. As for the CPU's, what would it add to a review of a card like this? Again, the purpose isn't to tell you "how many fps would you gain if you upgraded your CPU to a FX57?". It's to test this card versus the competition.
