I'd say try un-overclocking and benchmarking in windows to troubleshoot what the real problem is. The GT240 is a capable entry level gaming card just like its twin, the 9600GT. It should handle most modern games just fine at 720p resolution, and a few even at 1080p with medium settings and no FSAA. It may not be a mainstream performer in 2010, but seeing as they're often available for around $50 AR they are still a fair value.
No announcement yet.
