Thats great programming realy :-D
I've highlighted your problems and why this isn't a fair test...
Also; "dual core" + clock speed does not help with working out performance - a new i5 2.4Ghz could toast a 3+Ghz Core2Duo at least, perhaps some early i5s as well. Hell, the processor in my old MacBook Air (1.4Ghz i5; turboboost to 2.5? I think that was it...) is quicker than the one in my PC, and that's a Core2Duo that was pretty good for its time...
You want at least 4GB of RAM; ideally 8 for playing games. It won't help if you're running a 32bit OS (Windows 7 and after auto shipped with 64bit with 32 being an option; but before that you needed to go out your way to get a 64bit OS unless you had a Mac) but after that it should help. I'm not hugely knowledgable on video cards, but Nvidea cards are probably a cheaper alternative only if bitcoin idiots are buying up all of the ATI cards because of some weird feature in their GPU, so you'll get a better bang for your buck. If its a total update and you have the cash and case space, consider an SSD for the OS and Apps that you'd use - it probably wouldn't help with FPS but it just makes the whole computer run so much quicker that I couldn't go back to a PC with a HDD in it...
