I am looking at replacing my current graphics card, EVGA GeForce 9500 GT, PCI-Express, 2.0(x16), 1 gb DDR 2. Here's my problem, or confusion. If you look at a card like the EVGA GeForce 9800: EVGA 01G-P3-N988-TR GeForce 9800 GT Video Card - 1024MB DDR3, PCI Express 2.0(x16), DVI, HDMI, VGA Now look at another card: EVGA GeForce GT 630 02G-P3-2639-KR Video Card - 2GB DDR3, PCI-Express 2.0(x16), 2x Dual-Link DVI-I, 1x Mini-HDMI, DirectX 11, OpenGL 4.2, Single-Slot, Fan I am getting confused when I look at pictures of the spacing of the pins on the boards connector to the mother board. The 9800, like my 9500 has the pins run evenly from the front of the card to the back of the card, with no gaps. The GT 630, and others that I have looked at, have wider pins, with gaps at intervals in between. I haven't been able to find any documentation or reference to these differences, and don't want to screw up a purchase.
