I voted for non-SLI mainly due to the cost factor. This is because, when considering a SLI system, one has to buy a SLI motherboard, which are more expensive than non-SLI ones, buy another graphics card, and maybe who knows, buy another power supply of higher watt rating and which will have extra molex connectors. On the other hand, upgrading to only a new graphics card and overclocking the existing processor and increasing the RAM will be cheaper.
