There is no such thing as an "i2" . I assume you referring to a Core 2 or Core 2 Duo perhaps. Regardless, if you're saving for a new system, no it's not worth it replace the cpu at this point. The money is best put toward the new system. Also, clock and core count are two different things, and what you want is a newer architecture primarily, then cores and clock speed.
Sorry I'm a bit new to all this stuff.
and yes I do mean Intel core Duo not "i2"
AMD mentioned that everything is all tied together including the chipset. so i guess i was just wondering if I install this graphics card will it help my PC run games faster? I just assumed that part of the problem is that i didn't have a graphics card. Or again, is it just worth waiting?
Yes, a dedicated video card will help your games, but if you are planning on buying/building your new system soon, get something approrpriate to a modern system. It will be overpowered for you current system, but once you get your system it will fit right in. Just don't wait too long to upgrade, or get something that will be obsolete if you upgrade soon, again ways to waste money.
