I recently bought an xps8000 from dell. the graphics card (geforce gt 220) is mad loud and seems to be struggling. they've replaced the fans once and made no difference. im looking for a upper mid/high end card. i use the comp for vids/games nothing to extreme. will be upgrading my comp case and psu to antec 900 se and 750w+ psu
dell xps 8000
Processor Intel® Core™ i5 CPU 750 @ 2.67GHz
Memory (RAM) 4.00 GB
Graphics NVIDIA GeForce GT 220 Gaming graphics 2811 MB Total available graphics memory
Primary hard disk 500gb
screen is LG Flatron w2253tq "22inch"
i use 1920x 1080 resolution
With the power supply I think an ATI 5670 would be about the best you could do. What's your budget? A new PSU and a gtx 460 together would run you around $250-300usd. The 5670 is around $90 most places i've seen.
750w is already overkill unless you are going to be running two cards at once. How many watts you actually need depends on what card you get and that really depends on what you want to spend. If you can afford it this is a great deal and comes with 3 free(and actually good) games; http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
A 500w PSU of a good brand(Corsair, Antec, Seasonic, ect.) should handle the card just fine.
Yeah, unless you are doing a lot of HD video editing or perhaps music production, something that specifically uses a lot of ram then the average person won't really see much benefit from more than 4gb of ram.
