Then power off, install the new card, plug the monitor cable into the new card, and restart into Windows. At that point install the latest Catalyst package, restart, and you should be golden.
- What I would do is download a program called "Driver Sweeper." Install it on your system. After removing nVidia drivers, boot into safe mode. Open driver sweeper, check "nVidia - Display", "nVidia - PhysX" and whatever else has nVidia on it, click "analyze", then click "clean" to remove whatever is there. This'll remove any and all traces of nVidia drivers on your system so it doesn't get confused on what GPU to use. After that, I would turn the computer off and install the card. If the BIOS doesn't automatically switch to the video card at next bootup (which it should), connect the monitor cable to the onboard GPU and then switch the graphics to the card from within the BIOS. Start windows, and let it install the basic WDDM drivers
(otherwise you may have installation problems; I did without installing those first). Then, download and install the latest Catalyst Control Centre drivers over that. Installing CCC drivers may be problematic for you; it's certainly been problematic for me before. Sometimes the control center doesn't even show up, or it takes 12 times to install the drivers properly. ATI drivers are finicky sometimes
- Don't worry about the prices on NCIX, if you bought it with the sale price on your shopping cart then it should still be the sale price when you make final payment. Trust me, I once bought some cans of compressed air and cleaning materials there; a few days later when they were actually in-stock, the sale price had expired. When I went to the store for the final payment, I was still charged the sale price from the previous sale. NCIX also doesn't usually process your order on non-business days (i.e. weekends, holidays) so you may have to wait till the weekdays before the entire order is ready. They should send you an e-mail when everything is ready for pickup after. If you would like to go 5770, you can cancel this order of course, or you might be able to send the sales team ticket to swap out the 5750 for a 5770 in your order.
- A 5750 can be overclocked to 5770 levels and performance, but a 5770 can be overclocked even further
if you don't want to wait just buy an am2+ board that will be compatabile with your current CPU, overclock it
- This may be a viable option for you if you notice bottlenecking; an AM2+ motherboard that is capable of overclocking will take your current AM2 CPU and a future AM3 CPU such as Phenom II.
- brettjv is also right, even if your CPU might bottleneck the 5750 it's still a huge difference from an onboard 6100. An upgrade from the GMA 900 to the still low-end HD 3450 on my old PC was a huge improvement nevertheless
Hopefully that wasn't too long to read
