The Radeon HD 4850 will pull between 110-145 watts (depending upon who you trust).
Your 7600gs will pull around 25 watts.
At a minimum you need to verify that you have a quality >80% efficient 450w power supply. A 500w would be much better. The HD4850 should come with an adapter that will power the video card thru a 4-pin molex connector.
Download and install
HW Monitor. Run the program and note CPU temp and voltage.
Download and install
CPUz. Run the program. Your CPU should be 2200MHz, your HT speed should be 1000MHz and your ram speed 366MHz.
Read up on your BIOS settings in your manual. Learn how to reset your CMOS. Under the advanced tab in the BIOS select 'Jumperfree'
1) @ AI Tuning set overclocking to manual.
2) @ AI Tuning set CPU Freq to 219 MHz
3) @ AI Tuning set PCIe Freq to 100MHz
4) @ Chipset tab set the ""CPU<->NB HT, NB->SB HT & SB->NB HT"" speeds at '4x'
5) @ CPU Configuration tab disable 'Cool & Quiet'
6) Save and exit the BIOS.
The computer should restart and load Windows. If you have a problem you must reset the CMOS.
When Windows launches open CPUz. Your CPU speed should be 2410MHz, your HT speed should be 876MHz and your ram speed should be 401MHz. (AMD memory speed is 'double-pumped' so you RAMs will be running 802MHz)
Open HW Monitor and check your temps.
This should be simple enough. If you have a problem you may need to slightly bump your cpu voltage. It would be to your advantage to run a stress test on your computer to load the CPU 100% so that you may monitor your temps....
You most likely will be able to OC higher but that will involve reducing the memory ratio, more voltage tinkering, and would most certainly require stress testing and temp monitoring.
