Ok, to me its a touch and go situation.. But others maybe more Inclined to bite the bullet and go for it, but i have 2x GTX470 and wouldnt see a massive improvement wit a 9800GT as a dedicated Physx card (From what ive seen/been told)
With your system however, you'll likely see major improvements over mine in terms of FPS/Quality/Physx
I just realized that that my motherboard only has a total of 16 Pci-e lanes. Does this mean that it'll be divided into 8x and 8x (8x for HD 4890 and 8x for 9800gt)? And if so, would I notice a bottleneck with the 4890 only being able to use 8 lanes?
I not 100% sure on this, but i think the performance difference between 16x and 8x is about 5%?? I dont know weather if this is just based on SLI scaling, or weather this is based on all cards in lanes..
