However, as mentioned above, a fast CPU is not required for TKaraoke. TKaraoke is a single-threaded application so TB can be beneficial to TKaraoke. The i3 and below processors don't support TB. TB allows this processor to go up to 2.93GHz when the CPU's base frequency is only 2.4GHz. Intel i5 CPU - Supports Turbo Boost (TB) technology.
Nvidia dedicated video card - 512MB (Nvidia GT 330M, not 310M in cheaper models). HDMI output - hookup to big screen TV 1080p 3. I think this laptop gonna be great for TKaraoke. I just ordered this Sony Laptop to use with TKaraoke. Good mixer and speakers - The most important thing in karaoke is the sound! Big screen TV - LCD or LED that supports 1080p is the best. Memory is needed for newer OSes (Vista/7) so 2GB of RAM is good enough. Large memory size - TKaraoke only requires about 50MB of memory and depending on your song collection size, I don't see any case where TKaraoke would require more than 100MB of memory.
High resolution screen - When hookup to the big screen TV in dual-monitors mode, the laptop screen resolution doesn't need to be high to show the "Song List" window - any resolution 720p or higher (including 1280x800) is good enough. Big screen size - TKaraoke supports dual monitors and you should hookup the laptop to your big screen TV for best karaoke singing experience. Large hard drive - TKaraoke supports network drives so you can save some money on the laptop hard drive size. Any dual core processor is good enough (Intel Pentium Dual Core, Intel Core 2 Duo, Intel i3, i5, and i7 are all good). Fast CPU - TKaraoke doesn't require a fast CPU. However, USB external sound card can be purchased for around 100USD. Decent sound card - most laptops under 1000USD don't have dedicated sound cards. Your video card should be ranked top 150 in this ranking list. Dedicate video card - avoid integrated cards if possible. HDMI/DVI output port - important for high quality hookup to big screen TV.
