When I play high end games like far cry or doom 3 my machines lags like crazy, when I go to open doors it will pause and the graphics are kind of glitchy. In Doom 3 I have the graphics set on medium or high quality and the graphics seem to clip, no artifacts just 'clip' I dont really know how to explain it better than that.

MSI 9800Pro flashed to XT @ 400/355 for some reason i get artifacts overclocking this card, I have a thermaltake Giant III on it with a case fan blowing over it all and it still wont evenr each XT speeds.

You need a gig of ram, this will stop the hitches when doors open and cut your load times in half. Your card is NOT an XT so why would you think it would do XT clocks? If its artifacting its probably the VRAM, try some vantec solid copper ramsinks.
I think its an XT because it has a R360 core, so it IS an XT, I flashed the bios to the medion XXL bios and it is now an XT card with 128megs of ram. I have a thermaltake giant III cooler on it as well as ram sinks.
Doom3 uses some very large textures, in high mode it only compresses these a bit and it ultra mode it does not compress them at all. Therefore you need huge ammounts of video card RAM. Yours only has 128meg, you need 256 for high and 512 for ultra.
That doesn't mean that your particular chip is suitable for XT speeds. Also, the 9800XT has faster VRAM at tighter mem. timings, another significant issue. They choose the XT chips based on factory tests, not simply on the number of the core.
Freezing at the doors in doom 3 is "texture thrashing" which involves lack of video memory. Really cannot avoid that even when upping the cache in the cfg file.
After flashing the AGP card and you get snow then you need better cooling solutions on the core. Snow could also be a result of lack of voltage to the core for the clock speed but you are below xt speeds so that is not it. Artifacting could be normal side effect for the 9800s using the r350core, notice this in 3dmark03. I cannot play my core on my 9800pro-xt past 405 without snow showing up in Doom 3.
In your case, glitches are defiantely not good. Flash the card back to pro and run stock and OC ot XT speed to see if it still does it. If you dont have ramsinks on the AGP card then please do it.

I already bought new ram, I now am running 1.25 gigs in dual channel with tight timings. I didnt flash the card to XT I just changed the card ID in the bios to an XT, the bios is still factory. I dont get artifacts unless I go past 400/365 even though I have a thermaltake Giant III dual heatpipe cooler on it. So basically the only thing I can do to run these games on high settings is to buy a new video card? Even though I jsut spend $350 on this 9800pro?
Get the Humus Tweak (just google it). It really cut down on the "freezing" when opening doors etc in Doom3. The tweak is for ATI cards. Also make sure you have at least the Cat4.9's (IIRC), they supposedly have a Doom 3 tweak in them too.
