Help on this decision

Hi, recently my xfx 9800gx2 started acting up so I sent it back to xfx, now they told me that they can replace it with the ati 4890. DX is higher on the ati .. 15 thumbs up but it has no shader clock which would probably result in lagging with shader on.. say in a game like crysis. Am I correct? Now my question is, should I make this exchange deal or wait untill they get a 9800gx2 replacement which they probably wont get or get the HD 5850 standard edition for paying extra $100?

Specs 9800gx2 standard edi.

Bus Type: PCI-E 2.0
GPU Clock MHz: 600 MHz
Shader Clock MHz: 1500 MHz
Stream Processors: 256
Texture Fill Rate (billion/sec): 76.8 Billion/Sec
Memory Interface Bus (bit) 512
Memory Size (MB): 1024 MB
Memory Clock (MHz): 2000 MHz

Specs HD 4890 standard edi.

Bus Type: PCI-E 2.0
GPU Clock MHz: 850 MHz
Shader Clock MHz: 0 MHz
Stream Processors: 800
Texture Fill Rate (billion/sec): Billion/Sec
Memory Interface Bus (bit): 256

Memory Clock (MHz): 3900 MHz

  1. So your options are trade your 9800gx2 for a 4890 or wait for a replacement or get a 5850 for $100. correct?

    The 4890 dose not have a shader clock because it uses a completely different chip archatecture and cannot be compared apples to apples with Nvidia cards.,1680.html?prod%5B3249%5D=on&prod%5B3260%5D=on&prod%5B3214%5D=on

    The even trade for the 4890 seems fair if you want instant results.
    Where as if you wait for a replacement card you would get the same performance but you will have to well, wait for it to come back.
    The trade for the 5850 + $100 is also fair in my opinion. A new 4890 will cost you ~$200 and a new 5850 ~$300, ~$325 for an XFX a difference of $100-125 if you look at it that way.

    Do you want more FPS in your games/future proof with DX11? What are your computers specs so we can make sure you can get the most out of the 5850. If you want to have your computer up and running the fastest then the 4890 is your choice. If you can afford to wait then the 9800gx2 replacement is for you.
  2. I hear you loud and clear thanks. I guess Ill go with the 5850. My specs are

    intel core 2 duo E6850 3ghz
    evga nvidia nfoce 790i ultra sli
    ultra x3 1000 watt atx power supply
    4 x 1gb ddr3 ocz sli 2000mhz
    vista 32bit

    I will upgrade the computer, put in 8 gigs of ram and get a better cpu in the future.
