A good CPU should do the trick, so if you are planning on replacing it then just make sure you get something that's worthwhile as opposed to getting a low end CPU with a view to OC'ing it in an attempt to achieving big boy performance.
well the thing is that I am a musican/studing so I don have that much of an income but I was looking at two upgrading packgages
first one for aprox 2000 skr about 200 bucks alittle less http://www.komplett.se/k/ki.aspx?sku=604570
second one aprox 350 bucks http://www.komplett.se/k/ki.aspx?sku=495976
If I buy the first one I can get at least 4gb ram more but its a amd x3 445 and thats like low/midrange I think but maby its enough?
The second one has an i5 and quad so its alot better? but would the x3 be enough? I Just want to be able to play me2 with good performance and Mafia 2 and bfbc2 at like medium but whitout monster fps drops
