More about please selecting graphic card 550ti 7770 6870
  1. Radeon 7770 is a good option and its about the same as a 6870. And yes power wise you should be able to run any of these graphics cards you have listed on that PSU
  2. ....No the Radeon 7770 is about the same as the Radeon 6850, not the 6870.
  3. ower Consumption (Max TDP)

    Radeon HD 7770 80 Watts
    Radeon HD 6870 151 Watts
    Difference: 71 Watts (89%)
    Memory Bandwidth

    In theory, the Radeon HD 6870 will be 87% quicker than the Radeon HD 7770 overall, due to its greater data rate. (explain)

    Radeon HD 6870 134400 MB/sec
    Radeon HD 7770 72000 MB/sec
    Difference: 62400 (87%)
    Texel Rate

    The Radeon HD 6870 should be a lot (about 26%) more effective at AF than the Radeon HD 7770. (explain)
    Radeon HD 6870 50400 Mtexels/sec
    Radeon HD 7770 40000 Mtexels/sec
    Difference: 10400 (26%)
    Pixel Rate

    If using lots of anti-aliasing is important to you, then the Radeon HD 6870 is a better choice, by far. (explain)
    Radeon HD 6870 28800 Mpixels/sec
    Radeon HD 7770 16000 Mpixels/sec

    Bus Width 256-bit 128-bit

    but why my system supplier is telling you will run it any of the listed card
    he say go for cool master 550 fx is he making me fool to get his unit sold
  4. HIS 7770 iCooler 1GB GDDR5 PCI-E DVI/HDMI/2xMiniDP
    SAPPHIRE HD 7770 GHz Edition 1GB GDDR5
  5. get a hd 6850
    its the card to get!
  6. will it work with my psu mentioned earlier
  7. HD 6870... nuff said.
    Your lacking though. 2GB isn't enough these days if your a gamer(I assume you are since you are buying a mid-high end GPU). I suggest buying another 2GB stick
  8. yes should work fine
    my friend has same psu hd 6850 works nicely on it !
  9. but the problem is that i dnt have 6850 available in my country :P
  10. first upgrade your psu and then go with 6870 if you can.unfortunately you have one of the worst power supply on planet which is capable of damaging your system.a quality 550w is enough for a single card setup.
    and also upgrade your ram to atleast 4GB.
  11. i think i havent found any problem with ram issue its works smoth not a very high end gamer normal user but will upgrade soon
    Which PSU Will u suggest
  12. Yeah I suggest this:
    RAM is cheap nowadays, you can grab a 2GB stick for like $20(DDR2 is cost more)
  13. ^+1
    The Corsair CX600 should be perfect for that build.

    Like the others said, the HD 6870 is the way you should go.
    From a GTS 250, a GTX550Ti, would be little to no improvement, an HD 7750, maybe a minor 5-10% upgrade, a HD 6850, should see a significant boost, and a HD 6870, even better.

    And buy more RAM. If I'm not mistaken, you'be got an extra slot for adding another 2 GB stick, so do that.
  14. card ?

    The HD 6870.
  20. You have received excellent suggestions. PSU, RAM, then GFX.
  21. Best answer
    My advice:

    If you can, get a new PSU and a 6870. But that could be out of your budget. So my idea is get a 7770. It should run fine with your PSU. But also, upgrade your RAM. 4 GB would be the minimum, while 8 would be ideal. RAM is cheap these days.

    IMO 7770+Ram is better than 6870, even if it somehow manages to run on your PSU.

    Good luck choosing.
  22. What type of RAM do you have?
    It could be DDR2 or DDR3...
    EDIT: Its DDR2 get this:
