I see alot of peeps that have their 1700 or 1800 O/C'd to 2.4 - Is this possible?
Possible but not probable. Depends heavily on your overclocking environment (i.e. memory, power supply, etc.)
And with the high end cooling you recommend?
With the cooling mentioned above or even better, a SLK-800, you should get the best results obtainable using air cooling. I don't want to give out Gigahertz estimates because once again, it depends heavily on the overclocking environment. But, I would say that on average you would obtain better overclocks with the XP 2100+ Thoroughbred Processor (OEM) from newEgg.
What video would you recommend? I see alot of others are saying that the nVidia 4200ti 128 is about the best deal price/performance wise now?
For price/peformance, I would agree with that. Ti 4200 is a good buy. Especially since many of them overclock very well. Some folks here are overclocking ATi Radeon 9500 128MB Non-Pros to 9700 speed and beyond. Not garaunteed, but possible.
Also is the Samsung Memory as good as the crucial?
The Samsung original tends to overclock better than the Crucial memory. But, if yer really serious about about overclocking, go with Corsair.
On the Mobo, I have used ASUS on all of my Intel boxes and have always thought they were the best out there.
Abit is awesome. In my opinion, the best AMD motherboard is a Abit board (Abit NF7-S) and the best Intel Pentium4 board is from Abit (Abit IT7 MAX2).
Just out of curiosity, what is your rig specs?
I'm gettin by with a 1700+/ATi 9000 NP system. My next build will be built upon the Abit NF7-S.
