Want to upgrade video card, not sure if powersupply can handle it

Hello All,

I currently have an BFG 8800gtOC 512
I was thinking of upgrading to one of these 2 video cards:

The XFX 4870 1gb
http://www.xfxforce.com/en-us/products/graphiccards/HD%204000series/4870.aspx

Or the Nvidia GTX 260
http://www.xfxforce.com/en-gb/products/graphiccards/200series/260gtx.aspx

Im willing to spend $250 if someone thinks there is a better upgrade for a better value at that price feel free to let me know.

My issue is, im not very good when it comes to the power issue, i remember the first time i upgraded i bought a video card that was too powerfull for my 350 watt, and the second time i didnt have a power supply that had the extra cords for teh pcie stuff. This time i am a little afraid that i dont have the juice to run these cards so id like to make sure before hand.


My current powersupply is the OCZ GAME X Stream 600w:
My Motherboard is a P5B deluxe
My cpu is E6600 2.4 (@3ghz)
I have a Creative Xtremegamer sound card
1 WD 750gb hard drive
1 WD 160gb Hard drive
1 Maxtor 80gb hard drive
1 DVD DL Burner

Will have have the power to run either of these cards.

I don't turn off my computer for weeks at a time if that makes a difference, If anyone could give me some advice id appreciate it, i dont plan on buying the card for a few weeks, i only game at 1600x1200 and ive been hearing that upgrading isnt absolutely necessary.

  1. your psu is fine for those cards it has more than enough amps on the +12Volt rails

    Thanks, im not really good with that side of the technical stuff, and ic ant afford to upgrade both powersupply and card.
  3. Im really confused right now on the 4670 1gb vs the gtx 260 216, i i dont want to upgrade again for a long time, i dont know if the dx10.1 or sm4.1 is important enough, i hear they are both great cards, but its hard to decide which to get, doesnt seem lik there is any one glaring thing that can push one card to be better then the other.
  4. I would go with the one that has the best price presuming you are meaning the 4870 1GB

    Yes i mean teh 1 gb version.

    What about the gddr5 vs gddr3 is this a noticeable difference?
  6. One more issue, the size, does anyone know the exact size of 4870 1gb, and the gtx260 216, i have an 8800, and it fits in my case but its a little tight, are these cards bigger then the bfg 8800gt?
  7. Most all of them are dual slot, but about the same length as your 8800. Gigabyte is famous for making cards that are shorter than the reference design though.
  8. Thanks, i cant seem to find any mesurements online i guess im going to have to go to a store and look at the cards up close.
  9. I did a bunch of research on card dimensions and I can tell you all of the Nvidia GTX cards are 10. 5 inches long and the ATI 4 series are about the same. Both are dual slot of course.
  10. ddr5 vs ddr3 is a non-issue considering ones a 256bit bus and the other is 512.

    a gtx 285 has more memory bandwidth than a 4890.

    one factor you have to take into consideration when looking at card length with ati vs nvidia, ati card need to be plugged in at the back, this in essence makes them longer. nvidia cards plug in on the side. ati should really change that.

    Does that mean the buss sizes negate the ram types? I was leanign towards getting the 4870 but i believe the back back plugs may make it impossible for it to fit in my case. But the 8800 plugs in at the back as well, but i never actually measured it, im going to go do that.
  12. @ mrfoxx: Good idea to measure the case. Remember, the length is for the card only, so do n't forget to add the length of the connectors when measuring.
    The memory is a bit more technical: The Nvidia card uses slower memory but has a larger interface while the ATI card has faster memory but a smaller interface, the result is the two perform much the same, as the cards do in general.
    It is easy to get bogged down with the specs but I generally work to the rules given in this thread:

    http://www.tomshardware.co.uk/forum/page-264127_15_0.html
  13. I just measured my 8800 gt. between my card and the drive bay is 1.5inches of space, and after the plugs, its 1.2inches. I dont think i can fit either of those cards into my current case.
  14. Also, ive never used this website before, XPressCanada but its offering cards for some great values, but these prices make me unsure of the website.

    Im seeing the sapphire 4870 2gb for $279
    Xpress Canada - Video Cards > PCI-Express Cards > Powered By ATI : Sapphire Vapor-X HD ATI RADEON HD 4870 2GB GDDR5 Dual Dual-Link DVI HD Audio Shader Model 4.1 800 stream processor PCI-Express 2.0 Graphics Card.
    SAPPHIRE VAPOR-X HD 4870 2GB GDDR5 PCI-E

    And the 4890 for $284

    But i cant find the sapphire 2gb on ncix to price compare nore can i find a 2gb 4870 anywhere really, has anyone used this site before, and know if it isa legit set up, and if these are some good values?
  15. Sorry, i tried to edit the post several times and the page keeps telling me im not allowed to edit, i messed up the links:

  16. There is no need for a 2Gb card at 1600x1200 resoloution, 1Gb is fine.
    If you have not done so, look at the Newegg.ca and Tigerdirect.ca websites for more prices.
  17. My max resolution is 2048x1536, my current resolution is 1792x1344 i game in 1600x1200 in a window, would more video ram make a difference or should i still just stick to 1gb, and what about for future gaming i figure if i get this card now it should prolly last me a long time.
  18. The larger memory is only really useful at high resoloutions (especially with AA) but, the cards we are talking about would struggle at 2048x1536 even without AA enabled but a 1Gb card has more than enough power, and memory to run 1600x1200 or 1792x1344.
