Hi all Guys please help me out in deciding the video card. I have two options Xpert vision nvidia 9800 gt 512MB and Xpert vision radeon HD 4850 512mb. I'm getting nvidia 9800 GT for a lower price than HD 4850. So what do you think i should go for. How much is the performance difference between these two cards?? I've read that HD4850 beats 9800 GT the only problem with 4850 is heating issue which also can be solved by increasing the fan speed. Also one more question what difference does a manufacturer makes in performance of a video card?? is Palit Xpert Vision a good brand?? Please help me out please i'm going to buy the card soon. I've a low budget....so if there's not much difference in performance i think i should go for Nvidia 9800 GT.
