Trying to run ePSXe. Is my PC fast enough?

I downloaded ePSXe 1.7.0 and I can get it to run Final Fantasy Tactics but it runs very slow and is not playable. I have a Compaq Presario SR5110NX with a AMD Athlon 64 Processor 3800+ with 512MB of RAM. My graphics card is a NVIDA GeForce 6150 SE. Maybe I do not have enough RAM or I am using the wrong plugins? Any help is greatly appreciated.

Thanks in advance!

I run a system thats about equal if not worse then yours and I get full speed. I use pSX and epsxe. Maybe you should configure your video plugin and see if you can lower the quality. If that doesnt work, then see if there is a program that is taxing your CPU or try a different emulator. If you are worrying about saves, they can be transfered easily.

If that computer is a laptop.Then you are going to have trouble with speed.
