Current CPU - Athlon 3700+ Do i need to upgrade?

Hi, although my homebuilt gaming PC is only just recent i made a foolish mistake on my choice of CPU. I opted for the Athlon 3700+ to trim the price a bit, only realising my mistake after ordering... What i mean is the rest of my system is way above my CPU in terms of performance and power and so i think i may not be getting the performance that i could have been getting with a little more high range proccessor. Every time i look at my system typed out the 3700+ just makes it look so low range and crappy and so i am now reluctantly considering buying a better gaming CPU. First of all do you guys think my CPU is much too weak compared to the rest of my rig? If so what CPU do you suggest i get thats not too much of an increase in price and that suits my gaming needs?? I was thinking of maybe the Athlon x2 4200 :?: thanks for any advice.

Okay brilliant thanks for the advice

No need to upgrade, just overclock ! It won't turn your CPU into a dual core but I'm sure that you'll enjoy a nice boost in performance.

You're not losing alot of frames per sec. You could be better but we all could do better somewhere. The truth is as long as the games play great it doesnt matter. You have a top notch system with only a blemish. Big deal, dont worry about it. Besides enjoy the extra money right now. And a year from now go get a decent priced CPU. the 4000+ is currently the top price performance leader anyway. You aint far off.
