Hey there!
I am not sure if this is the correct area of the forums to post for a build but I will answer anyway
For $1,000 you can get a pretty good configuration. I will suggest one but of course if you want to make it truly your own throw some of your own ideas into the mix
CPU: Intel Core i5 (LGA 1150 socket) 4670 was my choice (could be different)
Motherboard: MSI Z87-G55 (again this is my personal choice. I love MSI but Asus is also a good choice)
Memory: 8Gb (2x4Gb) Corsair Vengeance DDR3 1600Mhz
Video: Evga GTX 760 2Gb GDDR5
SSD: Corsair Neutron 64Gb SSD
HDD: Western Digital 1Tb 7200RPM SATA 3.0
Power: Corsair CX600 600W (small wattage but it will do the trick)
Case: CoolerMaster HAF912 (a tad pricey but worth it for cooling and future expansion)
DVD: Some DVD reader/burner
Monitor: HE225DPB HannsG 21.5" 1080p LED Monitor
I got the total to $1,150.00 before rebates and assuming there are no sales or promotions going on. I would suggest waiting to see if there are any additional replies here to compare with and then piece the best one together for the price
