Would 7900GT SLI Be Bottlenecked By My CPU?

Thx.

So would a single 7900GT be sufficient to get max settings in all games at 1280x1024 res? My 7800GT can't even handle Far Cry with these settings without severe slowdown at times. I suspect for games like FEAR and Oblivion a single 7900GT would not be sufficient.
 
FEAR appears to be coded badly tbh, many people have more problems than they should with this game.

Frankly considering the current prices i would get this card ...
Connect3D ATI Radeon X1900 XT-X 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (3055) (GX-046-CO)
£311.32 Including VAT ** This Week Only**

[Same speed as the 7900GTX, but much cheaper]
 
Thanks for the recommendation but I have decided to get a single 7900GT for now. I have obtained one for around £220 including delivery and VAT. It seems they overclock extremely well and should perform not far below this ATI which is £100 more. If I want to upgrade further I shall get an additional 7900GT which will blitz the ATI model you have shown me.

If I had a Crossfire motherboard I might lean more towards the ATI cards, but the 7900GT seems to represent the best VFM to me atm, and I have an SLI mobo.

I'm still open to other opinions, and I have at least a week to change my mind whilst my supplier gets new stock.
 
If you have a 7800GT, the jump to the 7900GT (same speed as 7800GTX 256MB) may not be all you were hoping for in terms of a performance upgrade really.

The 7900GT is close to the X1800XT in speed.
The 7900GT is actually a fair bit slower than the X1900XTX in terms of single card performance.
As far as overclocking: all cards overclock. The X1800 & X1900 series are proven good overclockers.


The point is you may want to wait & get a faster card : the 7900GTX perhaps when prices come down, if you can wait that long.

Personally i have never seen the point of SLI (or crossfire for that matter), unless you get 2 cards straight away. I find that usually by the time i want a speed upgrade its cheaper to sell you original card & get the quicker next gen card. Especially now with Vista coming (DX10).

Anyway enjoy whatever card you get. :)

Strange my 7800GT can do Far cry 1680x1050 with full settings with HDR and AA+AF (with the new beta patch) and i never get slow downs ! Although the average FPS is 40's to 70's which is still very playable
 
Same here mate,no slowdown in Far cry,not that i've noticed anyway & i'm using a 7800GT.Although that's only @ 1280x1024

For me it is fine usually but at certain points becomes very bad. Most noticable is when Cryovision is used; on some areas frame rates drop to less than 10ps. It scores normal marks for it in 3DMark so I don't think there is anything wrong with it.
 
EDIT:

I have decided to go with the X1900XT. Wow - I didn't realise how good value they were here atm!

Can you tell me why to go for the one you mentioned though plz?

There is another one on sale for around £280:

PowerColor ATI Radeon X1900 XT 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (GX-060-PC)

I know it has a slightly lower stock speed, but will this effect its overclocking capabilities?

It was the cheapest XTX card & is a good buy.
However you are right the PowerColor X1900 XT should overclock to XT-X speeds (though they too overclock well) & it is cheaper, so it is a very good buy.
