Test Setup and Performance
The EVGA 7800GTX KO is without a doubt the fastest 7800 that we've reviewed so far. As expected, our tests ran nice and fast, and our framerates were high. All of our games looked great and played smoothly, but we've come to expect this from any of NVIDIA's 7800 graphics cards.This is the test system that we've been using:
MSI K8N Neo4 Platinum/SLI motherboard
AMD Athlon 64 FX-55 Processor
1 GB OCZ 2:2:2:6 DDR400 RAM
Seagate 7200.7 120 GB Hard Drive
OCZ 600 W PowerStream Power Supply
As we mentioned in the last review, we like to focus more on how these cards compare out of the box than with manual overclocking. This is simply because each card overclocks differently and you may not get the same results that we do when overclocking any given card. As expected, we saw that the EVGA 7800GTX KO reached the highest framerates of all the others, and we also saw the highest increase in performance from our reference card (which comes clocked at 430MHz, the same as the MSI's).
Manual overclocking is where the KO will, in a sense, break new ground. This is the first card that we've been able to test with its core clock set above 499MHz. We actually reached up to 515MHz initially, but dropped it back to 500MHz because of the issues that we mentioned earlier (it will give us the same performance). This high clock speed does allow quite impressive framerates and the numbers speak for themselves.
As has been the case with past 7800s that we've reviewed, there aren't any major leaps in performance between the cards. There is still somewhat of a tight grouping in framerates as you can see by the graphs. Just to summarize, in terms of performance (out of the box), we see the EVGA e-GeForce 7800GTX KO at the top, followed by the BFG 7800GTX OC, then EVGA's e-GeForce GTX (450MHz), and at the bottom is the MSI NX7800GTX (and NVIDIA reference card).

I am curious about the effectiveness of the new cooling packaging. I was wondering if you could perform the following test:1) Derate the clock speed to "normal" that is 430 / 1200.
2) Get the temperature profile.
I am wondering if the 7800 KO will run cooler at "normal" speed with the new cooling vs. a "normal" card running at "normal" speed.
Thanks for the time to put up these reviews, appreciated!

"As for the prices, it looks like the old EVGA e-GeForce 7800GTX with Battlefield 2 bundle is back down to about $500. This is good news for those on a budget."WTF? A $500 video card for people on a budget? You have lost touch with your readers.

Read the next paragraph, Questar.'"If you are on a budget – if we can call any computer part in the $500+ range 'budget'...." Obviously, they recognize that $500 is still a lot of money to pay for a GPU. Considering the performance relative to the 6800U which cost over $500 until June and is (http://labs.anandtech.com/img/plot/1472_182.png">still running $465), $500 for the performance increase the 7800GTX offers is not at all unreasonable. For budget and mid-range shoppers, it's a problem. I don't think they're really considering this card, though.

I totally preferred the roundups to the trickle...DerekWilson - Tuesday, August 9, 2005 - link
The problem with roundups is that they take time. We still don't have all the cards we would want to include. If we had to wait, it'd still be two to three weeks before we would have anything published on available 7800 GTX cards.As these cards are very expensive, we felt getting as much info out there as soon as possible was important for helping readers make smart choices on how to spend their money. If there's anything we can do to make the series better, let us know.

This card owns. It's just under twice as quiet as the BFG card and gets an amazing overclock.kalniel - Tuesday, August 9, 2005 - link
Anand are right that something screwy is going on with the internal frequencies - Nvidia themselves said it's a bit hard to define an overall clock speed for this card. What gets me is the relatively large increase in performance with just a 10/25mhz overclock - in most cases it seems as much a difference as going from the original eVGA card (a 40/50mhz clock difference). Don't know if some loop is just catching up in time with this extra increase or what.SpaceRanger - Tuesday, August 9, 2005 - link
Yup.. HardOCP had it right when they said that this thing is just an overpriced 7800 GTX because of an old designed TI4600 heatsink in a metal wrapper..Buying this card is NOT in your best interests..

hardocp and right should not be in same sentance.hardOCP is going the way of tomshardware (yes thats bad), they constantly pick up little things and go on and on and on about it. Like the Phantom console..i mean good lord did we really need to have that dragged out almost every week on front page? Its like they think everyone cares about it..news flash only you do! make a news blurb saying product is lame and move on! You put stuff like that on front page for days like its big news.
Bless RSS feeds, don't even had to visit hardocp anymore, since they just recap all the hardware news cut and pasted from other sites basicly.

The other thing I hate about HardOCP is that it's politicized. Every once in a while you see some right wing opinion of Kyle's about current events. Now I don't care if the reader is left or right but in my opinion politics needs to stay in the forums of a review site and off the front pages.
