If my computer Video Card performance is high and my processor performance is low will cause lag in game?

because i going to buy a new graphic card (Ge-Force 9800) but my computer is kinda old already about 2 year.

Processor/Ram: Pentium(R) D CPU 2.66GHz 2.67GHz, 1.43GB of Ram



my processor still good enough?|||your speed is plenty fast. if i read right it is a dual. most games recomend at most 2.6 that i have seen. but most are not even that high. the 9800 will probably be a 512 or a gig. so ram would be nice but not needed at this time. even if you run vista. most games only need 512 of ram to a gig. however most of that will be used by the built in ram for the video card anyways. it will help but not needed at this time. if you have the money then yes i would also add ram. again if you have a dual core or duo then you are perfect for now. single processor then the speed is starting to get a little slow for new games.





but if the speed is not fast enough then yes you could still lag even if you have a good graphics card. same with a bad or slow hard drive. my old laptop had a 5400 rpm hd and it would make games lag bad. when i put games on my external they ran perfect. but seems your computer is fast enough and again most games dont take more then 3 ghz single processor to run. and that is recommended. newer games are just now coming out. you can check with this too i will give a link. you pick the game you want to play and it will tell you if you meet the min or recommended. the only game i cant play is brother in arms according to it. however i play it just perfect. my cpu is 2.26 ghz duo. brother in arms needs 2.6 dual. however dual is not quite as good as duo and i think they messed up and put what they recommend. and not a min. also my computer has a overclock so i can run it at 2.5 when need to. other games like cod4 i think it says i can play min but not have recommended. cause it wont read when my computer is on overclock mode. for my computer it dont hurt it any to do cause it was meant for it. but other then that it kinda gives a basic idea anyways. so here is the site.





and with xp you are more then fine too. it only uses like maybe 256 mb. so you are running 1 gig or so just for programs and plus again whatever extra your new card brings.|||Ur Processor is good and if u buy new Ge-Force 9800 then ur pc works very good. no need to install new ram. but if u want better then this install 512mb ram and 450watt smps or one CPU FAN this thing make ur pc superfast like never before.

i use Pentium(R) D CPU 2.80GHz, 2GB OF Ram. i have geforce 8600gt graphic cardand my pc runs gta 4,prince of persia,tombrider underworld,nfs undercover without any truble.|||aka bottlenecking. You have a fast enough processor that you shouldn't have a problem.|||Should be plenty of processor power, in games the most taxed part of your system is your gpu. I would add a bit more ram though.|||you should add more ram thatll work
