Computer doesnt run smoothly on high quality graphics

Hey guys, Im playing this game called dayz i try to run it on max graphics it doesnt run very smoothly could this be because of my graphics card? here is a quick spec of my computer

Windows 7 ultimate
AMD phenom™ II X4 955 Processor (4 Cpus), ~3.2GHz
8192MB ddr3 RAM
ATI Radeon HD 4800 Series
ASUS Xtreme Design motherboard - M4A89GTD PRO/USB3
OCZ agility 3 60GB SSD

Its an old graphics card but worked well with crysis when it kinda first came out but dunno how well it would cope now. Thanks for any advice anyway

im guessing ym graphics card is GDDR3? Would i be able to buy a GDDR5 and put it in or is this a different fitting?

Im not amazing at these thigns but would just like to know and figure out what better graphics card i can buy :)

  1. Have you tried turning the graphic settings down?

    What is your budget you are willing to spend for a new GPU?

    What is the make and model of your PSU (power source unit)?
  2. Hello! Well im from the uk so willing to sepnd around £250. My psu is an antec true power 650 if thats any help? 650 watt output :)
  3. Ah and i quite like playing games with good graphics so its kind of the reason why :P xD
  4. Then I would go for a GTX 480 as that GPU can be found for around £200 such as the EVGA GTX 480. Since I'm from the US, I have not done much research on the prices from the UK, maybe some UK folks can give a better solution than mine.

    With the GTX 480, you would be able to max out most games at 1920x1080 and your PSU is fine to handle the GTX 480.
  5. EVGA GeForce GTX 480 1536MB GDDR5 PCI-Express Graphics Card (015-P3-1480-KR) [015-P3-1480-KR]

    its £190 pound so its a good price! :) Will this fit to my motherboard? ill get this pc mechanic to do the installing for me. i know its just plug in but i dunno if i need to install any other software bits and bobs.

    Appreciate this help very much my friend!! :)
  6. Yes it will fit fine, you can do it your self and save money unless he is doing it for free. It's easy really, just use Driver Sweeper to uninstall the old AMD driver and then reboot computer, then install the latest Nvidia driver and you will be good to go. ;)
  7. I see you could get a 6870x2 (single card)for around the same price that would smash a GTX480 in the teeth.

    see here:,2674.html

    Roughly %50 extra performance across all of Toms hardware testbench.
  8. link to one for sale:

    Power consumption is near 290W or so, so you can probably squeeze it into your power envelope too.
  9. You have to keep in mind that not all games scale well on Crossfire. the HD 6990 has trouble in BF3 and is out performed by even a GTX 580.
  10. ^^ true and yet it still maintains a 50% performance lead across the full test suite despite that fact.

    And we are not comparing it with a 580. Does it lead a 480 is the question we should be asking.
  11. I'm not saying it's a bad card, it's just that AMD takes a bit longer than Nvidia to get it right ;)

    If you check out this much more in depth review you can see that it even has a reasonable chance for some OCing on air too.
  13. I am just trying to find the absolute best performance per pound. Your suggestion is a very good card and I am sure the OP would be happy with it.

    I understand that "x2"'s are not everyones cup of tea. I have a 4870x2 myself, but since I only have a 1680x1050 monitor it is an acceptable setup to me.

    I have not had any problems with my card. and truthfully I would LOVE to buy the card I suggested if only my wife would allow it... And if you were to say, here have this GTX480 I would near pull your arm off in my hurry to snatch at it ;D.
  14. haha, I feel ya, that's a good GPU that you posted. Nothing wrong with that GPU. Maybe you should buy a new pair of shoes or a purse for the wife and blackmail her in order for you to get the GPU you want, lol
  15. Thanks guy i appreciate this very much, so this one on ebay is from essex, just so happens to be i live in essex too! :L Will this be a big improvement than my radeon 4800? :P
  16. Much better improvement, it would ROFL PWN your 4800 series ;)
  17. Lmao! Never heard that one before xD. Well ill order it and give you feedback how well it performs,
