The GeForce 600 series graphics cards of NVIDIA were released around the second quarter of this year, beginning with the GTX 680 which features the GK104 chip with the latest 28nm Kepler architecture. Without a doubt, the Kepler architecture brought in new and advanced features to GPU computing such as NVIDIA Surround (multiple monitors on a single card), GPU Boost, Adaptive Vertical Sync, and a lot more.
Being a high-end card, however, the GTX 680 is not for everyone as it is slated to capture the gaming/enthusiast market. Still, mainstream users should not forget that NVIDIA caters to everyone with their cards. Mainstream users are sure to be delighted by the more recent release of the 600 series entry-level cards of NVIDIA, the GeForce GT 610, GT 620, and the GT 630.

Here is an image of NVIDIA's reference GeForce GT 630. The GT 630 is one of the entry-level GeForce 600 series cards that NVIDIA has introduced.
NVIDIA's entry-level lineup of this generation, however, does not use the latest Kepler architecture. Instead, the GT 610, GT 620, and the GT 630 are equipped with the GF108 chip which is based on the older Fermi architecture. This might come as a bit of a shock to some but rehashing of older chips has been done before and not only by NVIDIA but also by AMD. While the GT 610, GT 620, and the GT 630 is still using Fermi chips, these cards can still blow away your integrated graphics for a very low cost.

We have samples of Inno3D's GT 620 and Zotac's GT 630 Synergy Edition. Let's see how these entry-level cards perform.
