today I found out that my 50" TV has a DVI port in the back of it, so I took my PC outside and hook it up with a RES of 1164x664 (Give or take a few pixels) Compared to my 17" NEC @ 1280x1024. Anyways I benchmarked 3d mark 06 and Scored about 1200 higher on my 50 in than on my 17 inch. Now im confused because I thought that I would my score would go down because I heard that SLI would only help if I was gonna run at super high res. instead it went up 
17" = 8900
50" = 10200
Please Some1 explain
