It's been over six months since Nvidia launched its Kepler architecture and we've finally seen the GTX 600 series enter more affordable price brackets, delivering a greater value every step of the way.

Having attacked the mid-range and upper-end markets, Nvidia has its sights set on the sub-$200 range, unleashing its GTX 650 Ti. At $150, the new arrival is roughly 34% cheaper than last month's GTX 660 and about 7% pricier than the Radeon HD 7770, which fetches around $140 depending on features and rebates. Here comes our full review.

Nvidia shook up the enthusiast GPU market last month when it launched its most affordable Kepler offering yet. At $299, the GeForce GTX 660 Ti was $100 cheaper than the GTX 670, while being just 13% slower. Likewise, the GTX 660 Ti was faster and more power efficient than the competing Radeon HD 7870, despite matching it on price.

Ever eager to keep AMD on its toes, Nvidia continues its push into the mid-range market with a Kepler-based card that is expected to retail for about $230 -- right in-between AMD's Radeon HD 7850 and 7870. The GTX 660 is based on the new 28nm GK106 that nonetheless keeps all the key innovations introduced by the GTX 680.

Although nothing used to match the GeForce GTX 670's price-to-performance ratio, its $400 entry fee remained a steep one. Gamers who wanted to spend less were left with the $230 HD 7850, the $300 HD 7870 or a card from Nvidia's last-gen lineup. Naturally, it would only be a matter of time before Nvidia tried to fill this gap with tons of hearsay about a GeForce GTX 660 Ti in the pipeline for a mid to late summer launch.

Well, we're here and the rumors proved true: Nvidia's new GeForce GTX 660 Ti has its crosshairs set on the HD 7870. Assuming it's priced competitively, the GTX 660 Ti seems like it could put a real hurting on AMD's offering, as it features the same DNA as existing Kepler products and boasts the same number of CUDA cores and texture units as the GTX 670.

A powerful graphics card is likely the most expensive component in your PC if you're a gamer, but with all current and past-gen GPUs available in the range of $100 to $500, it can be tough to pick the right solution for your needs.

In an effort to narrow things down, we're about to compare today's most relevant gaming cards that sell for $200 or more, testing them in a slew of games to see how it breaks down as we look for the best graphics cards for gaming at resolutions of 1920x1200 and 2560x1600.

After months of talking up its latest architecture, Nvidia reclaimed the single-GPU performance crown with its GeForce GTX 680, which outpaced the Radeon HD 7970 by about 7% in our tests. Kepler's arrival forced AMD to slash prices across its Southern Islands lineup.

The HD 7950 took a $60 cut to $399, making it one of the most tempting 7000 series cards because it has no equal -- or had no equal, we should say. Continuing Kepler's rollout, Nvidia has unveiled the GTX 670, which is priced against the HD 7950 at $399. Despite being $100 cheaper than the GTX 680, the GTX 670 doesn't appear to be much slower on paper, and that could spell disaster for AMD.

On paper, the GTX 680 has almost 200% more shader performance than the GTX 580, roughly 250% more texture performance, 90% more ROP performance and 100% more memory bandwidth. With the Radeon HD 7970 only being ~9% faster than the GTX 580, AMD appears to have priced itself into a corner this time around.

Because we didn't get a reference sample last month, our GTX 680 review will showcase one of the special edition products instead, meet the Gainward GTX 680 Phantom...
