In benchmarking numerous GPUs this past year (I have about 40 now), I've
definitely had the most problems when changing between different AMD cards.
Note that I have different OS setups for NVIDIA vs. AMD for each mbd
(separate SSDs), so it's not related to changing drivers from AMD to
NVIDIA or vice-versa. Rather, it's when changing from, say, a 5850 to a
4870. By contrast, for example, switching between an 8800GT and a GTX 580
is a much smoother process. Likewise, I find setting up and shutting down
SLI to be easier and more reliable than CF, especially 3-way/4-way. And
as you say there's the stutter issue which really was very obvious when
testing FC2 on 5850 CF.
> ... (refuse to stutter...LOL).
I've never been able to afford the latest top-end card when they've come out,
so I've repeatedly gone for a couple of older cards SLI: same or better
performance for lower cost, and being NVIDIA I don't have problems with
stutter (I really hope AMD can fix those issues, we need the competition).

I was going to be more specific but assumed you already knew - yes indeed
if I was playing modern titles that warranted the performance it would
be at 1440p (though the monitor I have is on the wrong desk atm) but the one
game I'd want to play on that kind of setup is heavily modded Skyrim, and
that really does benefit from more than 2GB. Read the
Skyrim pics thread,
there are numerous posts about the issue (one user has a system with four
Titans; his enormous mod setup results in as much as 4.8GB VRAM used).
As for other games, you're right that 2GB is just about sufficient for a
single HD display, but for this class of hw the current vogue in PC
gaming does seem to be more towards 1440p, often with multiple screens.
That needs more than 2GB. You're right about the 670 of course, but then
that's a card which is as you say too low down the performance scale to
warrant 4GB in multiscreen (I basically ignored the 600 series, waste of
time IMO), but it'll still help for single-screen 1440 with modded games
like Skyrim (have to say I rarely play PC games unmodded; part of the
reason why I like the PC platform is the ability to improve on standard
visuals). Also, choosing a card with 2GB because it has just about enough
RAM for the games of today doesn't exactly provide one with much in the
way of future proofing.

Most pro tasks are best done with a pro card, with additional 580s for CUDA
if such is sensible. Only a very few pro tasks run any better on a gamer card,
and there are dozens of other factors which mean gamer cards are often a poor
choice for pro users, from viewport accuracy, geometry precision and AA line
performance to customer support, reliability, ECC, etc.

I have different systems for each, and I do benchmark research with both,
plus some of my pro systems are not PCs (I have numerous SGIs, up to a
36-CPU Onyx3800 IR4). The right tool for the right job. ;D My 'pro'
3930K PC has a Quadro 4K and three 580s (mostly doing AE research atm),
though I'll be card-swapping to test other configs. My P55-based gaming
PC has two 580s (was two 560Tis until recently). There's also a dual-XEON
Dell T7500, but the 3930K smokes it.
I have a whole bunch of other PC setups for gamer benchmarking research,
but they're 'open' (ie. not in cases), eg. 2700K, 2500K, XEON X58, i5
670, i5 760, i7 870, 990X, various Athlon IIs, Ph2 965, Q6600, QX9650,
and so on. Often I mix & match parts to see what happens, eg. XEON + gamer
card (E5540 does surprisingly well), consumer chip + pro card (oc'd i3 550
is excellent for ProE).
Btw, re your comment about disliking stutter, I have a similar quirk when
it comes to gaming: I don't like playing on medium detail.
😀 Atm I'm
not playing sufficiently recent games to warrant the power of the latest
cards, which is why I keep obtaining a couple of older models so I can
max out the detail of older games (FC2, Crysis2, Oblivion, Stalker, etc.)
without busting the bank, and still have a high frame rate. I'd still
like to get a 7970 and maybe a 770 or 780 though for my benchmarking
research, but not yet (they're too new). I have a stack of other games
still sealed, which shall remain so lest I be tempted before finishing
those currently in progress, but I'm certainly looking forward to CoD WaW
with max detail settings and max AA/AF. 8)
