Use Everest again & look up your motherboard make & model number & your CPU specs please (model & clock speed, also FSB if it is stated). Let me know these specs & I'll tell you whether or not you can safely increase the ram speed.

Another thing to bear in mind is, if you have just added a DDR400 module to the existing ram module & the existing module was only DDR333, then you will won't be able to go higher than 333MHz even of the system does theoretically support it.

Athlon cpu's however only transfer 2 data items per clock cycle. So an Athlon cpu that has a real clock of 166MHz (for example), has an effective clock of 333MHz.
DDR memory has an effective clock speed of double the system's FSB (real clock speed). BTW, FSB = front side bus.
So in theory, a if the cpu has a real clock of 133MHz, the DDR ram will have an effective clock of 266MHz.
However, as in your case, thats not always so. This is due to the motherboards ability to change the RAM:FSB ratio. EG when both the cpu & the ram have a real clock of 133MHz, the ratio is 1:1. By adjusting this ratio however, the real clock of the ram can be changed independently of the CPU's real clock. In your case, the RAM:FSB ratio (133:166) is 4:5

To be honest, I am not a gamer & therefore not the best person to ask about specific video cards. You are right in thinking that overclocking can shorten the life of that component, so I guess the superclock one would be better than a slighly slower one thats overclocked to the same speed.
The only thing you may want to check though, before spending $300 on a new video card, is the max AGP rate supported by your system. The video card will only run at maximum performance if your system supports AGP 8x.
If you run Everest, it should tell you what the motherboards max supported agp rate is (This will be either 4x or 8x).
