Still running an AMD 6950 2GB
Running with a modded BIOS (6970 shader count, but 6950 clock speeds).
Probably my best ever tech purchase, still to this day running every game I own at 1920x1200res at decent framerates.
With the new console generation no longer applying a monumental brake on multi-platform graphics, I suspect I will need a new card soon, but for now it's perfectly adequate
Edit: noticed a fair few people are posting other systems.
Mine would be an AMD E-450 APU based laptop (1.65ghz CPU, 6320 GPU). Minimal spec really, but nice for lazing in bed with older games, utterly phenomenal performance per pound spent on it though, brilliant for a £300 laptop!.
What elite circles Techspot readers run in. If $200 cards are the most popular, you would hardly know it from these messages. I have an Asus HD7850 that was around $200 when I bought it. A few months later I picked up an MSI HD7850 Twin Frozr OC for $100 after rebate. The games I am playing now are pretty old (The Witcher and Deus Ex), so CrossFire is turned off. I'll turn it back on when I finish The Witcher and start The Witcher 2. Hoping to pick up Shadow of Mordor when it's on sale sometime-should help for that game, too.
My previous card was a Sapphire Radeon 6870 1GB, but I updated my build a month ago and I have a nice tasty EVGA GTX970 SC 4GB, which hasn't struggled on any game I've thrown at it so far! Considering getting a second card in a year or two when it starts to struggle.
Running x2 MSI NVIDIA GTX 970 Gaming 4Gs in SLI mode. Very nice they are too. Shame Assassin's Creed Unity is too flaky to allow me to use them in SLI mode. Really hoping it wont be long before Ubisoft provide a patch to rectify the issues.
