Eh??? Is the problem your score? 8,800 is a good score for a Ti4200, a guy on here posted his results (same spec as you) but with a faster 9500 pro, he got about 9,300! The fastest card you can get would probably get around the 10,000 mark on your system.
This is how i set my mind when i upgrade, for example, i put a 9700 pro in my system, dont expect anything amazing as its only a 1700xp, aim for a score of above 10,000 and get a nice suprise when i get 11,000 . Its bad practice to think you will get the same scores as reviewers do because they have the best components at the time and even if its the same cpu as u they probably have cl2 memory and supa fast m/b to support. Im off to bed now no more posting honest hehe...
Though your cpu is a 1.53 and mine is a 1.74 (but I've seen folks with slower cpu's top my scores at times)...I had started out with a score of 8,814 out of the box...I upgraded my mobo chipset software (via) and than upgraded my nvidia drivers (take drivers compatable with dx 8.1) and made sure I had dx 8.1...I diasabled v sync, AA, anistropic filtering and texture sharpening...I used either adapter default of 75hz for display refresh rate. Got good scores with both. You can try different settings for mipmapping...I've acheived different scores with each. Disabling vsync is a biggy. I've gotten many scores fooling around...my highest being 10630 (nice increase form 8,814). Also turn off background junk. Have fun!
Tell you what though, try downloading an over clock utility and see how far it will go. My 1700xp o/c's to 1800 levels with a mere 6mhz increase in bus speed and my 9700pro runs 337/324 from 324/310 and i get an extra 800 marks (12,000 my score now) and about an extra 5-10fps in games like morrowind with 4x ani and 8x anti on ,previously this game would struggle with all the settings maxed out, now not so bad . Just keep an eye on temps, take side panel off if you want more speed
