The Nvidia GeForce GT 730 64-bit GDDR5 is actually one of several variations of the GeForce 730 card, and it's the best of the group. An excellent choice for an entry-level card, the 730 is very similar to Nvidia's GT 640, but it comes with several enhancements, and is a more powerful card. The 64-bit 730 also utilises DDR5 memory, and it actually has a more powerful processor that the 128-bit version, making it faster than it's more-expensive sibling.
Utilising a re-invented processing architecture, the AMD Radeon HD 7770 is a more efficient and powerful card than a similar model produced by AMD in the past. The 7770 utilises the Graphics Core Next architecture, which can not only process instructions at a faster rate than before, but also has the ability to task each compute unit simultaneously, allowing each unit to process instructions at the same time.
Radeon's primary entry in the budget graphics card market, the AMD Radeon R7 260X features 896 stream processors and a 128-bit memory path. The R7 260X also features an onboard RAM buffer of 2 GB, and features 56 texture mapping units and 16 render outputs. It also comes with two DVI ports, a HDMI port and a DisplayPort that can drive up to three monitors.
One of Nvidia's top entries into the entry-level to midrange video card arena, the Nvidia GeForce GTX 560 is an excellent card for gaming and high-end video. Sporting two graphics clusters and streaming multiprocessors, the GTX 560 has increased the number of computing cores to 384, along with an increase of texture units to 64. All of this means that the GTX 560 provides better graphics than previous models, and is one of the best values for the money on the market.
Designed for serious gaming, the Nvidia GeForce GTX 750 TI might offer the best bang for the buck on this list. Very powerful yet efficient, the GTX 750 TI offers 640 processing cores and 2GB DDR5 dedicated memory. The GTX 750 is also re-designed to provide more powerful and nearly twice the power efficiency of previous models.
AMD's most powerful graphics card to date, the AMD Radeon R9 290X is based on AMD's Graphics Core Next Architecture, with 2,816 cores, 176 texture units and 64 render outputs. The R9 290X also features a huge memory interface of 512-bit and 4 GB of RAM, making it an excellent choice for high-end 4K gaming.
Featuring an upgrade in processor clock speed, the AMD Radeon 7970 GHz edition is still one of the best mid-range cards on the market. The 7970 GHz Edition is considered by many to be the best single-processor card on the market, and features 3 GB of DDR5 RAM and a 384-bit memory bus.
Based on the second-generation Maxwell processing line, the Nvidia GeForce GTX 980 offers perhaps the best performance available form a card with a single chip. It offers much better power efficiency and runs much more quietly, than similar cards. The GTX 980 also produces 2048 cores, 128 texture units and 64 render outputs. It also has 4 GB of dedicated RAM.
Regarded by many as the best graphics card on the market, the AMD Radeon R9 295X2 is designed with 4K and 1080p in mind. The R9 295X2 has two processors on the same circuit board, and boasts a faster clock speed than previous generations and similar cards in the category. Because of that processing power, the R9 295X2 features greater cooling than other cards, resulting in pretty efficient power usage as well.
The next-generation card from Nvidia, the Nvidia GeForce Titan 2 will be among, if not at the top, of the high-end graphic card market upon its release. The GTX Titan 2 will compete against new cards being release from AMD, such as the Radeon R9 390X, and will likely feature 2,688 processing cores, and will be over 30 percent faster than the Nvidia GeForce GTX 980. The GTX Titan 2 will be so powerful, in fact, that it will likely require liquid cooling.
