I've got a four year old PC that I'm thinking about either upgrading or replacing for Skyrim next month. Here are the specs:
E6750 Conroe Core2Duo 2.66GHz
ASUS P5K-E motherboard
MSI NX8800GT 512MB Nvidia video
4GB RAM
OCZ600SXS 600W power supply
I had it overclocked some but became unstable about half a year ago, so I brought it back down to default settings. It now has an issue where every great now and then it won't boot up properly, I get no video at all and the PC lets out 3 speaker beeps at boot up. Plus the occasional random lockup. I think the video card is acting up, but it happens very infrequently and when it does I just let it sit for awhile or play with powering up and down and eventually it boots up just fine. More of a random infrequent inconvenience than a serious problem I guess.
Other than that it's running Win7 with no problems at all. The newest games I play on it are Oblivion, Minecraft, Civ5, Microsoft FSX flight sim, and Starcraft II, and it runs all of them just fine. I can't max out SC2 but mid level graphics are good enough. FSX has to be dialed down of course, but it's acceptable.
But now with Skyrim coming finally, and Diablo III right around the corner, I'm wondering if my four year old system will be enough. I was thinking of doing one of two things:
1. Simply dropping a GTX560Ti 1GB card into it for about $220
or
2. Building a whole new I5 2500K Sandy Bridge PC with a GTX560Ti for about $800
Would a GTX560Ti even be worth it with an old E6750 processor, with Skyrim in mind? Or should I just bite the bullet and build a new PC?
