I'm currently running a i7-2600k Sandy Bridge on an MSI P67A-GD65. I bought two ASUS ENGTX460 with 768mb ea and running in SLI. I'm looking to step up a bit but don't want to break the bank. Looking at the charts I don't even see a benchmark of my configuration to compare. Any thoughts on a single card or pair under $300 to give it a nice boost? My primary gaming is racing sims like iRacing and rFactor or flight sims FSX, IL-2 and Falcon 4.0.
Where I could suggest cards such as the 660Ti the 7850LE I would say that if you are getting acceptable frames with what you are doing then I wouldn't upgrade quite yet. Unless you are looking to stay with one card with more VRAM which the newer cards do have.
