What temps should I expect adding a gpu to the loop??

[ScottyPimpin]

I have my i7 920 D0 @ 4.1ghz 1.28v in a single CPU loop.

MCP355 xspc top > Apogee XT > Black Ice Xtreme II Rad w/ 2200 rpm yates.

ambient temps about 74f/23c

Idle temps: 2 cores at 36c other two about 41c
Load temps: 56c and 62c

Looking to add a 5870 equivalent, waiting to see what cards are released in november really.. About how much heat will a GPU add to the loop?

I'm not into benching, just gaming so i'm not worried about everything running at 100% at the same time.

Here is Furmark running 1hr , notice gpu clocks and voltage and temps . This can give you some idea . The block is a DD-5970 using OCZ freeze everywhere except the vrm's .

that pic is pretty blurry but i can make out most numbers... what do your cpu temps look like?

I'm also thinking I need to re apply my arctic silver 5. My temps seem a little high so i'm going to check and make sure i'm getting good contact on the cpu wb when I get home today.
