1) The hassle I had getting it into the PC!
I have a large Antec PC case and I had to move a hard drive out of the way so the card would fit in OK. It is looong! Really, check the measurements of your case, the card is 275mm long - I thought it would go in mine easily, but was wrong!
Also , the card buffs up really tight against the memory slots. Meaning that to remove RAM you would have to remove the card first! Not sure if thats a fault of the card ( probably is, due to its length ) or my Gigabyte motherboard.
2) This one wont be so easy to spot by some people.
Without boring you too much with numbers, the OC2 is supposed to run at 626mhz GPU clock, 2000mhz Memory, and 1450mhz pixel shader.
HOWEVER, after I installed nTune from the nVidia website to monitor the card temperature. I discovered that the clock speeds were 600, 1800 and 1404 as opposed to the advertised speeds.
This was an OC1 card in an OC1 box with stickers on stating it was OC2. It has obviously failed to have had the BIOS updated at the factory to make it faster.
To cut a long story short, I have contacted BFG - who are happy to exhange the card. Their support seems quite good, but slow.
The other alternative is to flash the BIOS yourself. Warning - only do this if a) the card needs it and b) you know what you`re doing!
I`m yet to flash mine , but it should cure the problem.
Overall , the card is superb when running at the right speeds.
I play Oblivion on MAX detail at 1600x1050 with 16x anisotopic filtering and 8x anti aliasing, plus numerous other features. The game only stutters slightly now and again when outside. In the dungeons it plays like a dream, the creatures look fantastic with the high res textures and shaders.
Cant wait for Crysis!
Great card, but beware of the problems listed above.
