In this special roundup we have several reviews of NVIDIA's quad-SLI using the new 9800 GX2 video cards. NVIDIA released the 9800 GX2 last week, but due to commitments made to some of its OEM partners, the quad-SLI setups here were held under wraps. Yesterday that non-disclosure agreement was lifted and our affiliates have four reviews using cards from XFX and ASUS.
