It appears that EVGA will be taking up the Geforce GTX 650 Ti Boost challenge as has launched two versions, the reference clocked GTX 650 Ti Boost and the Superclocked factory overclocked version.
In case you missed it, the GTX 650 Ti Boost is based on GK106 GPU with a total of 768 CUDA cores and comes with either 1GB or 2GB of GDDR5 memory paired up with a 192-bit memory interface. The reference GPU clock is set at 980MHz but it can "boost" up to 1033MHz. The memory works at 6008MHz.
Although both announced EVGA GTX 650 Ti Boost graphics cards use the same blower style cooler, the Superclocked version works at 1072MHz for the GPU base and 1137MHz for the GPU boost clock while 2GB of GDDR5 memory remained at reference 6008MHz.
Both cards are compatible with EVGA's PrecisionX 4.0.0 overclocking/monitoring software and come with a standard 3 global warranty, something that EVGA is quite proud of. According to EVGA, both cards should be available pretty soon with a price of US $169.99 (€139/£123.00 exc VAT) for the reference one and US $179.99 (€147/£130.00 exc VAT) for the EVGA GTX 650 Ti Boost Superclocked version.
You can find them both here.
