All the benchies (even here on HWC) show the 275 on par, or outperforming the 280 in the majority of tests, for less $$$.

That is pretty good reasoning for this guy.
I haven't bothered to check that comparison at all........not sure how the 275 would outperform the 280 though....hmmmm...could be clock speeds and I'm sure that the little "out-performance" was at lower Res? Could you post the link which shows this? I'm curious now.....

From all the reviews I have seen the 275 is on average only 3-5 fps second behind the 285 at pretty much any resolution. Also like Sagath mentioned the HWC review shows this. This makes me come to believe the 275 is either on par or faster than the 280. The extra ram might help if you are playing on a 30incher but even then I bet it's negligible.

I think the naming scheme might throw some off that's why most automatically say the 280 is faster but the reviews don't show it. Then again most reviews only compare it with the 285!

From Nvidia GeForce GTX 275 896MB Review (hardwarecanucks.com)

They needed to thread a very fine needle when trying to find a happy medium between the GTX 260 216 and GTX 285 and considering how close this card comes to the GTX 285ís performance; we think they missed their mark
And funny enough, with 'only' a 448 bit bus, and less ram, at 2500+ resolutions, the GTX275 destroys the 4890, too.

I love my 275, the only (other) card I would consider on the market if I didnt own this, would be a 4770 for my (soon) HTPC build.

Really its a pointless comparison as the 280's have long been discontinued......
Not sure if I'm missing something, but looking at that Review it only compares the 275 to 285 (not 280) and although its not much, the 285 still comes out on top in the cases that I saw...

Anyhow....as long as your happy with your Cards that is all that matters in the end...

You're right. It was my bad to compare it to the 280 in my first post. I was thinking 285, but 'the brain' was writing 280. That being said, this week NCIX has 280's on sale, for a reasonable price of 350ish (iirc). I, however, would rather pay the $260, and buy a gtx275.

Like you also said, its a totally different ball game if you already own a 280 and are considering this factor for SLI reasons.

Exactly!!!!...you cannot SLi a 280 with anything but a 280.....in all honesty, as said, they're beasts, particulalrly when in Sli or Tril Sli.

As for those 280's on sale, they are the TR models, meaning limited Warranty.....my 280's will be up for sale in about 3 or 4 months time, right around the time we see the new GTX 3xx Series !!

I had a couple links to GTX 275s being directly compared to GTX 280s, and the GTX 275s beat them in pretty much all resolutions and tests, its the higher clocks and higher overclocking potential that gets them their though. Clock for clock I think the GTX 280 deffinetly has some superiority but like you said the GTX 280s are on their way out and are getting a little old =(

They're already out !

Its been almost a year since thier introduction....lets face it, the "lifetime" of these Cards is about 5 months ;)

Would like to see those comparisons though that shows the 280 being beaten in most Res and tests....
Personally my 280's are humming right along stable at 720 ./ 1458/ 1250 stock coolers. I know my 2 x 280's OC'd still provide for better performance than a single 295.

The one thing I do like with the new 275 / 285 is the reduced power consumption due to the 55nm introduction, this is especially good for folks looking to Tri Sli these Cards on a 1kW PSU.
In about 4 - 6 months time the GTX3xxx Series will be introduced and once again all these GTX 2xxx Series Cards will be "long in the tooth".....GPU technology moves ahead extremely quickly!

A couple of other things to consider:

The 280 - is 512-bit allowing for 141.7GB/s
The 275 - 448-bit interface, which allows only 127GB/s.

The 275 has 28 ROP units while the 280 has 32.

My OC'd 280's run Bandwidth at 160 GB/s

Bah I posted a link to one of the benchmarks in a thread you where following already let me find them again...

ZOTAC GeFORCE GTX 275 896MB Video Card Review | Futurelooks - Digital Lifestyle and Technology for the Masses

Ok nvm im an idiot, why they would inverse the names of the cards to the output of the graphics I DONT KNOW, but atleast that shows the 2 cards are VERY close, RJ what are the stock clocks on a GTX 280?

If it were me I'd get the 280 for a similar price. I remember these sort of debates with the 8800GTS/GTX 512 vs the 8800GTX. At the time they were close-but then came games like farcry 2 and GRID-after that it was no contest. Personally I think an oc'd GTX280, by virture of brute force, will hold out better than the 275 -although it does consume more power of course.
