I'm not looking to change the mobo if it's good enough and if it'll cost me a penny more (it seems every time I start a new thread on these forums, my total build costs grows and grows ). That's not to say I won't spend more on a mobo to get the most of my GFX card, I just don't want to spend any more money on my mobo if it's capable of doing everything fine as it is.
This is one of those where it depends on what you mean by "getting the most." Most frames per second? That depends on if you're overclocking your CPU or graphics card, or both. This is not an overclocking mobo. If you are talking about stock performance then it should be fine. Unless the motherboard in question has some crippled pci express lanes, then your card should perform just fine, paired with a decent CPU.
If you want more detailed advice I would say give us a full description of hardware including monitor resolution and we can analyze expected performance. The easy answer is that I don't think you have any need for concern, the HD 6870 is a solid mainstream GPU and the mobo is ok for most gaming situations.
I'll be using a relatively old monitor for a while after I purchase my build, but I'll be looking into buying a mid/high end monitor.
OK, this looks pretty good for the HD 6870. Should handle resolutions up to 1920X1200 with relative ease. I think you'll be happy with the performance, and with the core i5 you should have a very good experience. As long as overclocking is not in your future or sli/crossfire it looks like a good budget gamer.
It says it's compatible with with 1600, but it has (OC) next to the 1600. I assume that it means overclock, but is that something I'll have to worry about doing manually? I don't know how to/really care to OC something as soon as I get it.
EDIT: After thinking it over, I think I'll go back to the old mobo and use the RAM you suggested. I'll save a bit of cash. Thanks!
