The real question is however, "are SLI 7300GT graphics cards a worthwhile investment?" This is a very difficult question and in some ways I think yes they are, on the basis that once again you have to overclock these graphics cards. The benefit of two GeForce 7300GT cards such as the Gigabyte ones used in this article, is that they are passively cooled and produce very little heat, even when overclocked. They are also power supply friendly as they consume very little power, making them ideal for low-end systems. There is also the added advantage of multiple monitor support when you are not gaming.
