I second crossfiring your current card. Should be more than enough as well as being the best bang for your buck.

At this point in the product cycle, the answer is pretty consistently 1) 2nd of your current card, if it's within the last 2 generations, for XFire or SLI; 2) Single highest card you can afford 3) buying 2 lower end to mid cards to SLI.

The reason being is that option #1 is the cheapest, and option #3 eliminates future upgrade capacity, at a price that is probably the same as option #2.

i'm pretty sure cross fire doesn't support 3d make sure of this before deciding.

I switched from two 6870's to one GTX 580 so I can 3D vision game and watch 3D blu-ray movies on a single 120Hz monitor.

I was suffering from 10.2 AMD driver BSOD issues and also microstutter.

Though my FPS did drop some, (not much), I can handle all my gaming and no more microstutter, heat issues with top card, or driver issues since the switch.

There's con's and pro's for both sides.

For me though the 6870's crossfire was higher FPS they were 1GB VRAM, which is mirrored not combined in crossfire, my GTX 580 is 1.5GB VRAM is handling BGF3 beta, Crysis, Crysis 2 better.

I guess it's up to you. For 3D vision Nvidia does it better at a hardware level support rather like AMD through software and third party vendors. Since you haven't purchased your monitor yet you can choose from some really nice ones to support your Nvidia glasses.

If you weren't going with 3D anything, then I'd be tossed again since two 6870's are great performance for the money and slightly better than a single 580.

In hindsight, you will still have an open door to further your upgrade later with a second 580 next year when prices will be much less and your performance will be greatly higher than two 6870's. Though even by SLI'ing the 580's your back to those issues as I mentioned above.

I've had much simpler time with the single powerful GPU solution myself. Can't complain as I game everything out there anyway.

Samsung T27A950 uses its own 3D technology (software and hardware) and it does not support Nvidia/AMD's 3D. According to some reviews, it seems that it supports AMD cards (5000 series and later) better than Nvidia cards.

The ‘full 3D experience’ (120Hz ‘Frame Sequential’) is only afforded to AMD Radeon HD 5000 or above graphics cards with other cards relying on a 60Hz half resolution ‘Side by Side’ mode. Despite this 3D image quality remained ‘excellent’ on several game titles tested on several different GPUs (including an old Radeon X1650). It should be noted at this point that all modern GPUs can utilise 120Hz 2D output on the S27A950 over DisplayPort (cable below) and DVI Dual Link.

Alas, it is not 100% compatible with graphics cards. The TriDef driver only supports the 120Hz refresh rate and frame alteration on AMD’s graphics cards of the Radeon HD 5000 series or newer. Nvidia-based and older AMD/ATI cards are supported in the Side-by-Side mode at a refresh rate of 60 Hz, which effectively cuts the horizontal resolution by half. The SA950's native resolution of 1920x1080 transforms into a 960x1080 image shown to each eye. The good news is that this mode supports any graphics card.

Important Note:
T27A950 is actually a hybrid Monitor-HDTV (vs a pure monitor). OP might consider the SA950 model if his main interest is PC.

Q: The T27A950 is more expensive that means it's better right ?
A: No, the 'T' Monitors are really for TV it has no DVI port and is for someone that watches TV and plays XBOX this is not for computers.
