I just bought a Gigabyte 7800 gt NX78T256D-ZK, the card works great. Just had a questions on the V-tuner2 program that comes with it. When I start the program it shows the core clock at 275mhz and the memory clock at 1000mhz. Does that seem low? I thought it should of been more like 400mhz core and just a slighy higher memory clock. Any suggestions??
