iMac 27": 512MB 6770M or 1GB 6970M?

[dmax35]

Claimed to have a Ph.D title, craving numerical proof should've came first into mind instead of meaningless crap like that. I provided a valid data and all he could say was "don't believe this bozo and his flipping chart." .. Why not provide another valid data or argument to prove me otherwise?

EDIT:

Look man ... with all due respect, I don't mean to be a troll here. For goodness I love this forum and I'm trying to contribute the best I can.

I do feel silly and tired for debating over this thing again and again. But as I told you earlier, I have an iMac with 2GB VRAM myself, so I'm not trying to justify my machine or being envy and all.

I played BF3 on it months ago, set most to ultra on 2560x1440 (no AA/AF), I got a merely thin 20fps (almost stuttering). Compared to reports from iMac with 1GB GPU owners, I noticed roughly the same result, some 1GB GPUs even get a bit higher average FPS than mine, I could safely assume it's a redundancy.
So I do think even with 2GB GPU, high resolution, ultra texture pack .. my 6970M has yielded to its limit way before it could fill up the RAM. In short, 2GB is too good for it.

LMAO, I read you're now a iMac speaker expert as well. Please keep your love of posting on this forum going, it's keeps my fellow Ph.D friends entertained.

Certainly BF3 on ultra at 1440p is beyond the 6970m's capabilities. But slightly less demanding games and other functions could easily see a benefit from the extra 1GB. I'm thinking Starcraft II, Portal II, etc.

Nobody's doing benchmarks at this resolution. But the anecdotal evidence of improvement in some situations is plentiful and not just confined to this team of PhD's who may not even be terribly techy.

I may agree on that. But 6970M is not that powerful. It's barely-able to play games on iMac native. So I think having having more RAM for a barely able GPU is redundant since you can only play (at enjoyable level) on 1080p anyway.

Obviously you can't go wrong for having extra graphic RAM, but certainly not for $100. You better off with AppleCare or RAM upgrade. And like I said, Apple charges us 4 - 5x more for this measly upgrade, no better than buying RAM from Apple.

It can play games native just fine. Skyrim runs at 2560x1440 at 60fps+

I think not.

I think not.

It can. Well, mine does, alot of tweaking and testing with the graphics settings but skyrim will run very decently on 2560x1440.

Skyrim runs at 60fps on mine but I have to play at 1080p. Everything else maxed out.

If I switch to native resolution it's more like 40fps.

1080p with ultra settings is the best compromise IMO.

60FPS at 1920x1080 works for me on the 6970M, it dips a bit but then I do have a load of Mods installed in the game which highly enhance the graphics (see Nexus Mods).
