"Thermalright are no strangers to dual radiator tower heatsinks. In fact
they were one of the first to introduce the concept with their famous IFX-14
cooler. Although it never received as much attention as the much revered
Ultra 120 Extreme, the IFX-14 was a revolutionary design that allowed users
to attach up to three fans of varying thicknesses (25mm/38mm) so it proved
highly efficient for brute air cooling performance. However, the Ultra 120
Extreme has now been succeeded by the superior Venomous X, which proved to
be one of the best coolers we have tested here at Vortez, so it's now the
IFX-14's turn to undergo the same treatment. The result is the Thermalright
Some of you may notice that the Silver Arrow is reminiscent of the Cogage
Arrow and that's because the latter was designed by the same engineer team.
Cogage is a budget oriented company that falls under the umbrella of its
parent company, Thermalright. That's not to say that the Silver Arrow is a
direct copy of the Cogage solution because it has undergone several
refinements to deliver a highly polished product that is deserving of its
Thermalright heritage. The most significant difference is the inclusion of
Thermalright's latest TR TY-140 fans but more on that later."

Two HD 5770 cards perform better than a single HD5850 card and two HD 5850 cards perform much better than a single HD 5770 card. Considering the price of the two HD 5770s is nearly the same as a HD 5870 card I would suggest buying a single HD 5870 or HD 5850 depending on which price range. On the other hand, if you only have $160 a HD 5770 added to the system later will improve performance immensely in most applications. Two HD 5750s in Crossfire mode make for an attractive upgrade as well if you only have $130 to spend on a video card today.
