I didn't know exactly what forum topic this thread belonged in because it has three different things involved. Here is the question.. I am getting the XFX Geforce 6800gt and the Thermaltake Bigwater water-cooling kit. I heard you can fit the vga waterblock made by Thermaltake that is compatible with the Bigwater onto the Geforce 6800gt, but I wanted to hear from you guys if it was true. Two people said it can, so I dont know. Next, that wasnt the main question. Will the Bigwater cool this card good enough? I dont care if it is 'crazy' low degrees like some of your pro water cooling setups are, I just want to simply water-cool the vga and cpu with ease. Also, another main question is, I want to overclock the cpu (stock is 3.0e ghz prescott) to like 3.4+ and I want to overclock the vga card higher too. Will this Bigwater kit handle it. Dont tell me to just custom build one, because I heard that too many times. I just want a kit. I am starting out, so this is a good start with someone on a budget. I would really appreciate it if all of my questions are answered, and I would like to know soon as possible, because I plan to order my parts the next day, so I need to be sure about everything. Thank you.
