rpcdllc,
If you haven't already, please check out the minimum system requirements link over to the right ( ►).
Also, while browsers are different, and some can correct minor flaws, the sppeds between most will not totally correct the symptoms you are describing, and you might want to consider some of the other useful suggestions you will find in the forums by using the search box over there also.
gamebooster is a good addition (see google), shutting down all other running programs is another, a video card makes a WORLD of difference as well, but seems to be rarely discussed here. For those comfortable with it, there is also an option of a second hard drive (or a partition to dual boot to) with a clean OS installation, with nothing else installed other than a preferred browser, and AV program, and gamebooster. That's what I do, and meter skips are reduced by leaps and bounds.
