The C3 stepping is the new revision of chips. They tend to overclock higher than the previous stepping and is similar to D0 vs. G0 Q6600 situation from years ago.C3????????
If you have a PCI Express 2.0 x16 motherboard, do you need a PCI Express 2.0 x16 Graphic card, or will a PCI Express 2.1 x16 graphic card work in it also? I ask because I just noticed that my Motherboard is a PCI Express 2.0 x16 while my graphic card is a PCI Express 2.1 x16.
The 5870 is a higher end card and will give you better performance overall in games. AMD simply decided to confuse people by moving their mainstream series (57xx) up a step (68xx). It's a trade off though - performance for power and heat. A good power supply and a fan or two can take care of the power and heat issues so it all comes down to have much cash you have and how future proof you want your system to be.Or would this be a better CPU and GPU combo
