I am new to this whole thing in general so after trying to search the web for a few days I just decided to post a question on a forum. Basically, I am giving my mom my old computer which was an HP. It had the AMD 5600 dual core processor, 3 gb of ram and a visiontek 1550x 512mb pcie card that I put into it. I wanted a more serious gaming computer even though I don't game all that much and bought this to replace it. Link removed because of my first post. It is the ibuypower 528. I got it on sale for $559 also. So, how much performance am I going to gain here? I know the graphics card is a step up but as far as the processor goes, I went from a pretty good dual core to the worst quad core correct? Will there be a big difference? I also bought an extra 4 gb of ram to throw in the new one for the hell of it. Pretty much the only game I play is BF2 right now so how will it do with that? My old system ran it on med settings pretty good. I hope I can go all the way up in terms of settings for that game. Any other ideas out there as well. I will have more questions as people comment, I am sure.
