If you are looking for a killer gaming card, but find the 7800GTX too expensive, then you will want to check out the recently released 7800GT. It’s been scaled down to 20 Pipes and 7 Vertex Units but it still packs a massive punch. We are taking a look at the eVGA version, which comes pre-overclocked! Time to see what this beast can do.

Now that all the specs are out of the way, let’s move on to to see more of what this card has to offer.

NVIDIA chose a 400MHz Core and 1000MHz Memory, which eVGA happily overclocked to 445MHz and 1070MHz, respectively. This is a bonus, because those who do not want to risk voiding a warranty, don’t have an immediate need to overclock. Even though the card is pre-overclocked, it comes complete with a lifetime warranty. Of course, BFG offered the same for quite a while, so it was only a matter of time before another company joined the fray. BFG’s version of the card only overclocked the Core by 25MHz, so eVGA has the advantage here.

As already mentioned, the card contains 20 Pixel Pipelines and 7 Vertex Units. The card comes with 256MB 256-Bit GDDR3 memory, at 535MHz (Effectively 1,07GHz). The memory bandwidth can also reach an amazing 32GB/s. Lastly, the card is built upon a 0.11 process, and contains 302 Million transistors.

The 7800 GT inner workings are extremely similar to the GTX, so even though the card is scaled down, it has amazing potential. During the review, we are going to try to safely overclock our 7800 GT to see if it can reach GTX speeds, and keep respectable temps.

For those who are interested, here is a 6800GT and the 7800GT side by side. The 7800 is slightly larger, but is still nothing you will have to worry about. Ever since I’ve seen the size of the 6800GT for the Apple, I learned to never complain about size again.
