Hi there i wanted to know if this spec pc will be any good for frame rates in FS Intel Pentium 4 3.06GHz Processor 512MB DDR RAM 80GB Hard Drive 16x DVD Drive 48x CDRW Drive 128Mb GeForce MX 440 SE Graphics and also is it worth replacing the 128mb Geforce 4 Mx with a 64mb Ti4200 ? thanks

That will get you good FPS, but both video card choices you have listed aren't the best. An appropriate analogy would be if I had a champion racing horse|(your computer without the video card), and then I put 15 lbs of weights(vidoe card) on each of its legs when it was racing. Yes, that doesn't total a lot of weight, especially to a horse, but it would still slow it down some and it wouldn't perform at its best. :)Get an ATI 9x00 Pro, that will do you good.
