the tittle says it all. will my Pentium 4 @ 3.00Ghz bottleneck the 4850?

For example with the Need for Speed Underground 2, I played it perfectly with higest graphics. However, sometimes it laggs for 2 o 3 seconds and then great again. I guess it's my micro. What do you think?

yes, even top end P4's bottleneck even an 8600GT so yes it is bottlenecking the 4850.

thanks, I'll buy a Q8400

Indeed, i had a P4 system that i wanted to test this with and it ran almost the same (performance-wise) with the following 2 different graphics cards:

Sapphire HD 4850 512 MB
Sapphire Radeon X1300 Pro 256 MB

Though the 4850 DID run a little better/smoother, there was not much difference in performance... P4's suck even compared to a Pentium D

do you recommend me the Q8400??

no..i recommend P II or q9550

I recommend E8400
Or you can you go with the quad core for future proof

depends on what board you have.

My little bro has an Athlon X2 3800+ system with a ATI 4850. The system runs very slow because the CPU is killing the GPU's potential. The Athlon would wipe the floor with your P4 so I would hesitate about thinking of pairing the 2. I would look towards the Phenom 2 or Intel e8400 if it's mostly for gaming for your next system.

P4s were bottlenecking cards like the X1900 and 7800s!! Lol, I had a X1950 with a 3.2Ghz P4 then put it with a 1.8Ghz C2D and 3DMark06 score went up by 1/3!
Anyway, you are right to ditch the P4, and then you have to decide what to go for, which I suggest would depend on what you've got at the moment.
As you have a socket 775 motherboard you may just be able to drop a newer C2D or C2Q chip in, firstly check the CPU support list for your mobo model on the manufacturer's website. (If you can put a newer chip in then a BIOS update will proabably be necessary too - always do this in DOS)
If you cannot support any high end C2Ds or C2Qs then you will need to buy a new motherboard too, then this poses the question of whether to go i7, PII or C2D/Q.
I'm sure lots of people will have different opinions on this but my take is if your current mobo will take a E8400 for example and you have 2-4Gb of good DDR2 this will be the cheapest option, a Q9550 would be more expensive but would future proof a bit more and be better for heavy multitasking. If you nee a new mobo and if you have some good DDR2, 4Gb of 800-1066 say, then a newer 775 mobo like a good P45 or X38/X48 and a Q9550 would be a good buy, would give you the option of crossfire and would easily last you for the current i7 generation, or you could go for a similar PII setup. Or if you have the money now you could go i7 in the hope that that would last a bit further - this will of course be a bit more expensive!

I recommend Phenom II X4 940 which is much more powerful than the Q8400 with almost the same price! However, like MMclachlan said, C2D/C2Q will be better choice if they are supported by your current motherboard, as you won't need to pay extra for a new motherboard.

thank you very much, I have Mother ASUS P5KPL-AM, 2 gb ddr2 and I don't have money enough to buy a Q9550, because I'm from Argentina, so, I have already bought Q8200. I think I should Overclock it to get a better performance at gaming.
Could you tell me how to do it with the Bios version 0513 of ASUS?

Hi, you can download the latest BIOS and manual at . Overclocking should be easy by following the steps shown in the manual.

just up the FSB. Easy Overclock.
