most onboard grafix cardz sukzor
Here's a little lesson on grafix card memory use and system memory use as far as t2 goes. T2 will use around 180 megs of system ram, and by this I mean the actual game code that does not sit in your grafix card. The game code that sits in your grafix card is not so large, my guess is around 128 megs or so and this total will greatly depend upon a few things: screen resolution (higher res means more vid card memory taken up right off the bat), 16x anisotropic filtering takes hardly any more memory than without any anisotropic filtering, and the huge memory stealer is called antialiasing filtering. Antialiasing is the huge memory and bandwidth stealer.
The issue with systems that use onboard grafix is that system memory is also dedicated to use for video, and this is not good unless you have no other way to play. System memory is terribly slow compared to on-video-card memory for several reasons. Using system mem for video card mem adds more calls to the os and system memory stack that greatly increases latency that would otherwise not happen if the vid card had enough of its own memory.
Your system has an average memory footprint as well, and this is what is shown in task manager when the system is just sitting there doing nothing. This memory footrprint is entirely dependant upon what os you run, xp has an average footprint, vista has one, and so on.
Once you have enough memory to cover the os footprint and any activity that you put the system to such as games or office apps or whatnot, additional memory does nothing but waste electricity unless you use it.
Now with t2 being from 2001, the memory and grafix needs are fairly low yet when there's 60 players spamming away on screen it has a tendancy to stress even the newest vid cards, so if you can get a new vid card do it. Get the best one you canafford that your system will accept. And by accept I mean the system is either pci, agp, pcie or a derivative of pcie, you need to know what video bus your system uses.
There are several types of memory used in systems today. Most systems sold right now are likely running ddr3, and there are many speeds of ddr3 around, as well as ecc and so on. Then there is ddr2 with its various speeds, and ddr with various speeds and on down to dram and its speeds. Ecc mem is a type of memory popular with servers and high reliability work stations, ecc stands for error correction code, and the memory has the built in ability to detect and correct the most common type memory error- a single bit. The type and speed of memory for each system is determined by the motherboard chipset alone. Whatever the motherboard supports is what can be used. Then once you have the type of ram determined you look at the fsb of the processors used. Each cpu has what is called a fsb, FrontSide Bus. This is the channel in wich the cpu talks to the memory and vice versa. Cpus are usualy lenient as to what fsb they run at so one can overclock them or even underclock them if wanted or needed. But I prefer to run memory at the fsb for 1:1 ratio of mem fsb and cpu fsb.
