2x 8800gt in SLI graphics difference

[Acid_death69]

Hi,
Im thinking of purchasing another 8800gt and combining them in SLI. I was wondering if it would be worth it and would i see or notice a great deal graphics wise or anything like that. Would i get a better GPU instead for something like £100?

A little over £100 would get you a single GPU atleast as good and maybe better than 8800GT SLI without the reliance on multi GPU scaling.

However if you can get a second 8800GT very cheap and have an SLI board it does give you a nice boost for 1680x and 1920x res tho starts to run out of VRAM at 1920x if you turn the AA up too much. When I first ran 8800GT SLI I had a 1440x900 display and it was still giving 60+% scaling then everything ran silly smooth.

Not reaally worth it...You be much better off buying a GTX 260 or HD 4890

I got a second 8800GT a few months back. On an i7 920 at 3GHz it made the following improvements...

3d Mark 03
35692 55494 = 155%

3D Mark Vantage
6298 12373 = 196%

Crysis Demo
26 37 = 142%

GTA4
36 54 = 150%

However I took it out after a week or so as I didn't really need the improved frame rate, and my load power usage increased by about 150 watts - peak was around 540 watts and that was on a 480 watt PSU!) Also the 2 cards close together got hot and so both their fans would run at 100% after a couple of minutes.

In summary, good value increase that often gave better performance than a GTX 260 or 4870, but noisier and more power hungry.

sorry cannot believe one 8800GT could add 150 watts..... Could be very inefficient PSU there....

150W does seem like quite an unrealistic number for an 8800GT

How much faster would 2 x 5770 be over 2 x 8800gtx? .. hope this is not looked at hijacking his thread as its in a similar vein

2x 5770 are quite fast compared to 2x8800gtx.

Not only that but it uses less power, less heat, supports dx11 etc.
