the Intel Core i5-2500k Sandy Bridge 3.3GHz Quad Core is a very nifty little processor. I went with that processor for my custom rig and it runs like a dream. Only thing left is to get an Old republic Mouse....I wants it sooooooooo Badly!
Um..., i don't know about i5, and i definitely don't know about nVidia!
I actually built a gaming PC for a friend, it was:
Processor: Intel i7 2600K 3.4GHz, 4 Cores, 8 Threads, 8MB Cache.
Motherboard: um, actually i can't remember what it was but it was something high end.
Video Card: MSI ATI R6970 Lightning, 2GB Memory.
PSU: 1200W Cooler Master
Case: a Cooler Master that i can't remember what was its model.
OS: Windows 7 Ultimate X64, SP1.
Hard Drive: a 2 Terabyte WD Black.
Razer gaming Keyboard and Mouse.
And..., i wasn't fully satisfied with the performance of that Rig!
We were using it with a LED HD TV on 1920x1080 resolution and a 60Hz, and we were testing GTAIV with settings set to every thing at Max and when things got all crowded and stuff with cars blowing and police cars every where and roads crowded with damaged cars and stuff, trying to drive one of the fast cars on max speed running through all this trying to escape from the police and we could notice quit clear that the game is not as smooth when we are driving at max speed, there is like a frame drop, looks like a hiccup or a choke every few seconds, and i was like that's not what i expected from such a rig.
But, that was only with GTAIV, this could be a problem from the game even though it was up to date, also the video card's drivers was just released so maybe with an update it will get better, other games was running quite fine though, but i still need to see this rig with a SSD hard inside.
