The question is what is a good card to water cool? I don't want to pay much more than $400 for a single card or more than $300 a piece for a dual SLI setup. Would prefer to stay away from full cover cards and utilize a GPU cooler only with heat sinks on other parts of the card. I will probably use Aqua Computer TwinPlex Pro's with a silver base and a OC Aquastream pump that puts out about 4.5 Liters.
