Which drivers would be best for overclocking nvidia geforce 9800gt?

The stock cooling for the 9800gt have always been crap so replace that first before doing any serious overclocking. 700mhz core is to be expected and 1.7-1.8ghz shader. The mem is going to be the disappointing part as with any 9800gt. I got both 65 and 55nm versions, the 55nm is the best for overclocking. The EE or green editions are the worst for overclocking.

The worst temp that I ever had with my 9800gt was when the fan lost power and the card heated up to 121c before I had realized the failure. It ran with out issue for half an hour at those temps and still no artifacts nor bsod. Passive with a VF900 isn't the best idea.

Actually, here, I am not concerned about heating coz

When I try to overclock to higher limits it starts lagging or should I have to give it some time to make overclocked settings compatible???
I have latest drivers 258.96whql and Physx............before it used to get overclocked to max but after installing new set of drivers it has started showing it's colour.

yes, it is true.....if you believe

I have done that once and I don't recommend it and it is dangerous without the right proper clothing. The lowest idle temp that I had on a cpu was a meager 4c on air and this was in the middle of winter.

I didn't have to all I did was open the window one day when it was windy. Sure we may roast in 40c+ heat in the summer but on rare occasions we do get an arctic blast that can freeze the plumbing. I don't live in the UK unlike most of you.

Then what state rich boy? Come down to Texas and enjoy our heat and dry climate. I do not take kindly to city slickers.

I have been to Florida but down hear in Texas the heat can be deadly and in come places in the cities it can top 115f easily on a hot day. When you feel the heat through your work boots then you know its hot. I once had the rear view mirror fall off when the glue (old car) melted that mounted it on the windshield. On one occasion the transformer behind my old house overheated and vented. In the summer you better have a decent UPS if you ever want to live in Dallas, power failure is somewhat common.
