Hello. I have pentium d 915 dual core 2.8ghz cpu with 3Gb (667 Mhz) ram and i bought a gainward geforce 9800gtx gpu. I thought i could play the games in good fps but i am dissapointed. What it might be wrong ? Is my gpu not fast enough? Is my cpu which drops the frames? Is my soundcard onboard? Does soundcard affect game performance? I dond't know what to think. i try to use lower resolution even 1024x768 but i manage to gain a few fps (4-5) from 16080x1050 which i had. i think this is very strange. If it is my cpu i am going to buy a new set (cpu motherboard ram). What do you suggest me quad or dual core for gaming ? intel or amd ? I am also thinking to buy a sli mobo so in some months when i have the money, to buy another 9800gtx in and put it in sli mode. or should i shell my gpu and buy a better? But in all reviews i read before i buy it i see it is similar to 8800gtx and even with 3870x2. thants why i bought it. before i had gainward 7600gt golden sample. Does the other brands of 9800gtx like asus or bfg or xfx are better ? If you want me to run a benchmark to post the results to see my performance tell which i and i will run them. But in 3dmark06 and crysis the frame rate is very low. I also overclock my card to 800 1225 2000 but not a big difference only 1-2 fps better. Please give me your advise. Thanks.
