I recently Purchased a BFG 7800 GS OC AGP to upgrade my ATI 9800 pro that was in my older computer that I have for when friends or my brother comes over to play games. This computer still has some decent specs.

Pentium 4 3.2Ghz
Abit IC7-Max 3 Motherboard
1GB cosair Twinx cas 2 3200 DDR
250GB 16MB cache SATA HD
SoundBlaster Audigy 2zs platinum
and the BFG 7800 GS oc


I decided to try and OC this card and see what she could do. Well So far I am very impressed. Originally after a full load of Quake4 running for 1 hour with no OC my cards temp was 54c. So I decided to OC the card and I let the NVIDIA Drivers Detect my optimal Frequencies. It reported 480MHz Core and a 1.40GHz Memory Frequency. So I gave it a whirl and Let quake4 run under load at 1280x1024, 4x AA, High Quality and the NVIDIA Drivers set to High Quality too. Well after an hour the cards temp was 105c OUCH. One thing I did notice is that the fan on the BFG card was kind of wimpy so I decided to rig a 90mm fan i had lying around to it. ( nothing fancy I just placed it in front of the card to get air moving over the heat spreaders.) Well after another hour of quake4 the temp was only 54c. A very respectable temp so I say lets see how high i can go. So far I have pushed the card to 500mhz Core Clock and a 1450mhz memory clock at 57c after an hour of load. I am a bit hesitant to go much higher. The card is supposed to have a 430MHZ core and a 1250MHz Memory. How high do you guys think you can push these cards? I will get some Benchmarks and pics posted soon if people want them.

Edit - No I havent seen any artifacts or tearing yet either in Quake4 or Half Life 2
 
a few weeks ago on a particularly cold night (desktop near window) i got it up to 530/1.45 with stock cooling. open case fan.
 
all i must say is wow! very good OC for the 7800gs.. but a pci-e x850xt would murder it! ive seen a x850xt pci-e goto 680mhz core/ 1.35ghz memory! zoom....is all they were scoring aprox around 8500 in 3dmark05.. also a pci-e x850xt is about 180$ retail newegg

Yea, but the agp version to compare to the 7800gs is much much more.
 
well actually ive never seen a review of a OC x850xt against the 7800gs OC.
my brother had his at 580/1.23ghz and he was getting around 7600 in 3dmark05
also his was AGP x850xt.. the cards are very close in speed.. and trust me i would much rather have the 7800gs because of the SM3.0 although its ashame after all these years nvidia still released something that runs along the 6800 ultra and a x850xt pe lol
it seems like being such a suprise drop of the 7800gs, it would really be something worth buying.. im really dispointed in nvidia for dropping it with 16 pipes.. because the x850xt pe came out in 2004 something.. and it default averages about 6400 in 3dmark05,, and the 7800gs just came out 2006 and it default 375mhz 1.2ghz.... lol it averages about 5800 in 3dmark05.. very very sad.. seems like 2 years gap of the x850xt pe and the 7800gs.. nvidia could have dropped something to kill it
 
Maybe...but it could be that the AGP bus just can't provide the throughput that 20-24 pipes requires? Just a thought.
