Want to upgrade my processor

you had good system ( like mine in office ).. if want upgrade much total to next gen , keep your money safe it and .. just wait newer Gen with cheap, if you lucky may get Cut price .

i want to upgrade now can you tell me which is better than mine for gaming?

What is your current PC Spec ?

processor: Pentium(R) Dual - Core Cpu E5700 @3.00GHz
Ram : 2GB
Graphic card:nvidia GeForce8400GS 1gb ddr3
Mother board:Biostar G41D3C

IMO, the smallest step up from 3GHz Core2Duo worth considering at this point in time would be i3-3220 but that would mean new MoBo+CPU+RAM worth ~$270 total. For ~$30 more, you can kick it up another notch with i5-3350P.

Considering how ridiculously expensive DDR2 is today (3-4X the cost of DDR3), the platform upgrade enables significant savings there, since you will likely want to upgrade to 4-8GB RAM.

Don't bother. You need to upgrade motherboard too since yours is LGA775, outdated.

If it's for gaming, you should get a new gpu, not cpu. Your gpu is so outdated that even with a new cpu, you won't have much performance increase.

So wat shud i hav to upgrade now?List......plz.......................

Is there any best gaming gpu's under 100$

Nothing that I would recommend on LGA775.

If you upgrade to LGA1155, you could get a Pentium G2120 for ~$90 but this would only be 20-40% faster than your current system so not really worth the trouble. The i3-3220 which costs around $120 would be 30-80% faster which is more worthwhile when you consider that you are already looking at a ~$225 rebuild cost ($90 CPU, $100 motherboard, $35 8GB RAM) even with the G2120.

Edit: scrap that, hallucinated 'CPU'. GPU-wise, the sub-$100 category is being eclipsed by AMD's A10 Trinity IGP, nothing worth recommending there IMO. If you want something that isn't obsolete vs IGPs, you have to look at the $150 price point.

The gpu upgrade depends on what power supply you have in your computer. Tell me what the make and model is and I can make a recommendation. Likely a HD7750/7770 is going to be it.

If you want to upgrade the computer. This would be twice as fast as what you have now for $160.

With a $100 budget limit, there isn't much PSU worrying to do since there aren't many options outside the 50-70W range at that price point. If 20W is enough to make/break his PSU, whatever you recommend won't change the outcome much.

Since the OP already has a GForce 8400, it probably uses more power than any replacement he is likely to find under $100 today.

Well I'm not going to look up the power usage of a 8400GS, but I already know the power usage of today's gpu's off the top of my head, which is why I am asking him what psu he has.

Just get one of these and you'll be happy for a while. I'd get the XFX, it comes with a free game and it has a lifetime warranty.

So,If i upgrade my gpu and Ram can i play codmw3,Battlefield3........games with high settings?

Yes. Just upgrade GPU & RAM and you should be able to play those game on a particular setting depending on the GPU you decide to buy.

You will however have to find a setting that doesn't give you any lag or hinder playability

I thing Any Ivy Bridge Pentium will be a good choice but they are not launched yet - as far as I think.
