I'm building a budget system for medium gaming and planning on using a 19" widescreen LCD and an old 17" CRT I have lying around as dual monitors. I am planning on getting a X850XT PE. I just plan on playing CS:S on medium quality and maybe some other games. How well can I expect this to perform? I realize 2 monitors puts extra work on the video card, which is why I'm asking. I'd like to get at least 40fps stable on CS:S (with medium quality I guess). Will this be very likely, or will the second monitor drastically affect performance?
