Resolution, in and of it self, is a pretty minor component of VRAM usage. It affects mainly frame buffer sizes, which are far smaller than textures used in most games. Only truly enormous resolutions, or huge amounts of AA are really likely to make frame buffer sizes the deciding factor. There are still cases where you can see a difference between 2 and 3 GiB, but they are extremely rare in unmodded games.

Memory bandwidth probably matters more, but most games aren't going to be memory bandwidth limited, even on a 770.

Most dominant? What about games like Dirt?

Also, 3.1 fps in that test is still a proportionally larger differential than the other tests you chose to show.

As of Catalyst 13.6 drivers, AMD's multi-GPU frame time intervals are still extremely inconsistent.

I personally do not consider any AMD Crossfire setup to be usable atm. Hopefully this will change soon, but it's still reality as of this post.

You can use amd radeon pro,it's much better than nvi adaptive v sync(for CF set up). I personally use it.

"Aside from a few dropped frames and a handful of spikes when the test changes scenes, our dual-Tahiti card enjoys much smoother sailing. In fact, the end result is often better than what you'd see from a single graphics card, with virtually no micro-stuttering left.

The RadeonPro software is more complicated to use than Nvidia's hardware-based solution because you have to manually create a new profile for each and every game. But the results speak for themselves. This is nothing short of a revelation for the folks who pin the scalability of their gaming machines on multi-GPU configurations, but hate the idea of micro-stuttering. John Mautari, the utility's developer, deserves big thanks from the crew at AMD, to be certain. "

770's are cheaper than 680's from some vendors in the UK biggrin.gif

Thinking about doing the same keeping both my 570s. Will see how the prices pan out here in Aus.

I'm thinking you do not need to go past your current GTX 660 without upgrading your overclock at least and more than likely your platform.
you get visible bottlenecks when you are on lower resolutions than 1080 (10+fps), but i pack now 1440p so single card with quad core @3.4ghz with turned on XMSAA will get in 99% cases full gpu usage.
I reviewed several articles and i am not going to spend 600eur so that i get in most games @1440p 70-90fps instead of 50-70fps when LCD itself can show only 60fps.
Here are the reviews

It depends on the game.

Crysis 3 when i max it at 1080p uses 1.8GB of gpu ram.
yes Crysis 3 is the one game where CPU bottleneck is strongly shown but you still get playable 35+avg fps, i did the campaign and didnot played multiplayer much.
other games in reviews above have comfortable avg fps (45-55), and in my case all i target is 60fps @1440p. you dont need more fps at this resolution

as i said Crysis 3 is one of few games where my cpu is enough to play the singleplayer campaign through. and i wont spend 600eur on new cpu/mb/ram to play 70-90fps instead of 50-70fps in 95% of games. so right now i am feeling being gpu bottlenecked as its always 99%. i will go eihter with 770 4gb or 8970 6gb

i5+decent mobo+8gigs of DDR3 costs about 350€ (or a lot less if you happen to find a good deals or used parts, I recently sold my 2500k for 140€), not saying you MUST upgrade, but it wouldnt cost 600€, not even close smile.gif

i am now on single graphic card motherboard so to buy a cheap single card gigabyte motherboard would make no sense if this is to be an upgrade. then the 600eur contains also custom cpu cooler for higher oc and i7 (why i5? to get bottlenecked again few years once 20nm are out?). so it does add up. when i do things i try to do it properly smile.gif

Even if we consider that 1 GB is reserved for the OS(es), and some of it will be used for non GPU related tasks in games, new games for consoles will want to show the benefits of a new generation of consoles and thus start using a good amount of high resolution textures right from the beginning, so expect at least 2 GB of (V)RAM to be used right from the start, so now the question is: what will the experience of a GTX 770 owner be in one year, let alone in two years, before the upgrade cycle comes ?

I'll say it again, the saving grace for this card is the price, but ultimately, and given AMD's clear efforts and successes in driver improvements and commitment to gaming (TressFX, Never Settle Bundles), their hardware makes the most sense for people on non yearly upgrade cycles.

people are still talking about console RAM 42 pages later?

8GB is total RAM

next time you open up Crysis 3 and max it out, check how much regular RAM it uses in your task manager

deduct that amount from the total

the OS alone will take up at least 1GB, but probably 2GB

deduct that from the total

what are you left with?

there are no secrets to textures, if they were big enough to require 3GB of VRAM or more, there wouldn't be enough GPU power to render them at acceptable framerates at 1080p

the RAM will probably be used like a RAMdisk to ensure fast load times and smoother experiences in regards to UI to compensate for the lack of SSD
