Hi guys Im sure you have been asked this Question before, But Im desperate to get up and working again. Problem is the 3870x2 went dead , no visuals at all, I got a so called expert to look at it and he put a new graphics card in, HD5450 Its nowhere near in comparison. skyrim is like slowmotion. I dont know a lot about computers but i am going to sort this myself ,with a bit of help . I am not sure if my computer details will come up, so here they are,Dell XPS Premium Q9400 Core 2 Quad,2.66Ghz,2660Mhz 4 cores ,4 logical processers. Memory 3GB Dual channel DDR2 800mhz[2x1024MB/2x512MB]memory.The graphics card was a radeon 3870x2 which is DDR3/4. Power 425w.
I would like to install something as good or better without doing to much else as I am no expert, have done a bit of research on web and keep coming up with Radeon 6870 or 6850 , These numbers mean nothing to me, so would appreciate any help given .
A quality 500W power supply is enough for most single GPU PC's, if you plan on doing any upgrading later or any overclocking then grab a 600W+ unit.
With power supplies you'll need to disconnect the PSU cables from the other components in the computer and unscrew the unit from the back of the PC case, then remove it all together. There are plenty of guides online (google/youtube).
Which of the two cards would be best for gaming, Not to worried about price
