you said that zalman wouldn't have ("of") made a waterblock for the 177W vga card because the reserator struggles with the 95W cpu.
faulty logic because one is not like the other. one is a waterblock, the other is a radiating reservoir. (reser-voir + radi-ator, reser-ator). the reserator is more or less as good a cooler as is a stock cooler. even medium-high heatsinks cool better than that. so whatever the reserator does is not a good argument to stand on and say that 'they wouldn't of made a waterblock for a 177W card'.
you also expressed doubts as to whether the card as sold on ebay has a selfcontaining, complete, cooling system, because you couldn't see any barbs, ignoring that there are holes on there. so one would say that it is apparent (it appears, i.e. you can see it) not a self contained system.
it is not a selfcontained water cooler. leave it. it's a waterblock without the barbs, on a 8800gtx
yes jakg i remember about your dad's reserator. it's a really bad cooling system. only good because it is dead silent.
medium watercooling is better than good aircooling. go watch some reviews. http://www.hexus.net/content/item.php?item=781&page=5. bad watercooling (i.e. something like the reserator1) is more or less as good as medium aircooling. medium aircooling is whatever stock coolers are on the cpu.
here's another comparison between one of the best heatsinks, the TRUE against a budget watercooling system, the hydro50whatever (60 quid for a complete cpu watercooling kit when usually only the cpu waterblock is that much. look at dangerden etc) http://www.hexus.net/content/item.php?item=19073&page=7
either the 8800gt or the 4850. they are more or less the same performance. maybe the 4850 has lower powerconsumption but i do not know much about nvidia anyway
you see the holes in which the barbs are supposed to go in.
the listing is wrong.
what you see is a 8800gtx with the zalman 8800gtx waterblock but with its barbs removed.
did you forget your brain at the pub today dude? snap out of it.
besides, just because the crappy reserator struggles with a cpu what does that mean? that a watercooling block is inadequate? if that were inadequate... then aircooling would be better? is it opposites day?
your overclocked 64x2 is not puny. you probably have it at about 2.6, am i right? it's a cpu made for gaming.
a psu working at 50% load is slightly more efficient than at >=70% so a 500W psu coupled with a 300Wsystem will generate a little bit more heat than a 600W of the same quality.
the raceabout has become quite driveable in the last versions. tried it yesterday, in fern black, the most turn heavy track and was pleasantly surprised!
i've seen psus work at 110% of their reported power ratings, but that is not reason to suggest components that "worked for me so it must be ok to do so generaly". You might get away with straining a piece of hardware, you might not.
a psu working at 90% will be under strain and if it is meant to develop problems, it will do so sooner, possibly taking with it other components. if it is working at a lower workload, it might not do so before the next upgrade (which means ever)
you want to risk your components' life by getting a psu that is just within the ratings? go ahead, i won't stop you, it's your pc, your money and your decision. But i would not suggest for someone else's pc to go that way.
i would change the cooler, if i were you. not that that card puts out any amount of heat that should worry you, but it's a prime candidate for passive cooling.
as always, accelero s1rev2 (only problem is i don't remember if the agp version that you have is supported or if the pcie-agp bridge chip needs extra care)
