I recently bought a new GPU, wondering how much my CPU will bottleneck it.

GPU:
SAPPHIRE Radeon HD 6850 (1GB)

CPU:
Intel Core Duo E7400 @ 2.8Ghz, Stock settings. (Should I overclock it, or will it be fine?)

At lower resolutions (< 1650x1050) the CPU will probably bottleneck you some, but at higher resolutions the CPU will become less of a bottleneck as the load shifts to the GPU. I would recommend overclocking your CPU to give you some extra headroom.

Yah you should O.C. to minimize the bottleneck.An O.C. over 3.1ghz should be optimal.

Get a good heatsink and push it to 4Ghz. I just sold a friend of mine a build with the 7400 added a single rad water loop oc it to 4 and let him have it.

Depends on what resolution you play at.

Either way, I would overclock it. Not sure how good the stock cooler is but you should be able to get a decent overclock.

in a lot of cases it will depend on the games you play. a game like battlefield bad company 2 needs more than 2 cores to enable it to use more than 50 percent of the gpu power.
while crysis would run quite happily at much higher settings as it only needs a dual core.
overall i would recommend you switch the core2duo out for a quad of 2.4 or faster.

We don't even know what games he's going/trying to play.

We need more details to assist you.
