We recently acquired a Nvidia 7300 GT. It is a video card of good quality, much better than the plates of the series Nvidia 6xxx and 7xxx LE or GS. The basic difference between them, apart from the processor working frequency and quantity of memories, is to use the Turbo Cache. Despite being a good business name and attractive, if your card has Turbo Cache, it is worse!
Turbo Cache is the ability to use the card's memory to complement the computer's video memory, among other things. For more RAM to your computer has, this option will be terrible for the overall performance of the plate! Why? Because the "problem" to share memory is not the quantity but the speed of access! In the case of the plaque with CT, the speed will be very limited and several games will not run very well. In other words, access to the video card memory is faster than access the main RAM.
For example: the card Geforce 6200 LE runs GTA San Andreas WITHOUT antialiasing, that is, with quality almost minimal. The 6200 LE does not run Crysis, no way!
Have a Geforce 7300 GT, which has 512 MB of RAM on the card and do not use the memory of your computer, run GTA San Andreas no more than the resolution of 1024 x 768. This same plate, runs Crysis at least! But at least wheel, and gives you play.
Are you curious? Crysis is one of the heaviest in the game today (January 2008). Lower the Crysis demo and try to play a game. It is good and Vicia!
Returning to the subject ...
The Nvidia 7300GT is a good sign, except for a query: it heats up too! Or does not go by the hand, even with the office open!
To solve this problem of heating, simply adapt a cooler or two on the waster heat that is already on the plate! Will be fine and warm you will better protect your investment.
In general, if you scratch the disspador that comes into your card, it will void the warranty. As soon tie the two coolers with disposable ties, which do not cause any damage to the waster. If you ever have a problem, just take the lead and coolers at the store.
Look at the photos below as is the 7300 GT with the coolers installed.
