Noob asking about upgrade, help greatly appreciated.

Hello this is my first post here, i am looking to upgrade my graphics card and am not sure of compatibility with my current setup, any advice would be appreciated, i know only the basics in computing. My current setup is

O/S - Windows vista 64 bit
CPU - Q6600 quad core 2.40ghz
Memory - 4gb ram
Motherboard - nForce 750i SLI ftw
GPU - Radeon HD 5500
PSU - 650w

The computer is around 3 years old i have had to change graphics cards 3 times, originally i owned a 9800gtx then onto a GTS250 now i own the Radeon 5500.. Seems the graphics cards have got worse due to my knowledge and bad advice.. I was looking at these 2 cards http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1163&products_id=17198 Radeon HD 6850
http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1164&products_id=17194 Radeon 6870 but was unsure of how the would fit in with my current system.

Thankyou!

More about noob upgrade greatly appreciated
  1. What brand is the 650 watt? Also a 6870 is awesome, but for the price 6850 is best for price 6870 is best for performance wise.
  2. 6850 would be a major upgrade over any of the 3 graphics cards you have owned.
  3. (Off Topic)Also what is the 5500 sounds like a fake card, that 250 is MUCH better probably.


    Anyway yeah a 6850 would be a HUGE upgrade.
  4. While I agree with the other posters, you may want to look at the GTX460 or GTX560 seeing as you have an SLI board.
  5. (cough cough) and over clock the 6600 a little to like 2.7 (cough cough)
  6. Thankyou for the replies guys, much appreciated the 650w psu was ordered for me by a friend, i had a look at the case i can't really see a brand name apart from a blue "K" on it.. Sounds like the 6850 is worth looking into, would it be alright with the rest of my hardware? i will also take in consideration looking into the GTX cards, thankyou. also about the 6600 i would have no idea where to start on how to overclock it. thanks again.
