I am looking to build my first PC, specifically for KSP (although it would be nice to revisit old favorites like Fallout 3 with mod support). My laptop barely runs it at lowest possible settings; it works alright but lag sometimes results in physics glitches - the same rocket that has flown a dozen times exploding on the launch pad. I have heard that the optimization of KSP makes it so that additional cores do not provide any benefit, and I should instead focus on single core performance. So rather than going to one of cheap the 6 or 8 core AMDs, I am thinking the i3-4130 ($130) or i5-3350 ($180). My total budget is around $800. So, I would end up with something like this and drop the SSD to account for the increased price of the intel chip PCPartPicker part list / Price breakdown by merchant / Benchmarks CPU: AMD FX-8320 3.5GHz 8-Core Processor ($129.99 @ Newegg) Motherboard: ASRock 970 Extreme3 R2.0 ATX AM3+ Motherboard ($84.99 @ Newegg) Memory: A-Data XPG Gaming Series 8GB (2 x 4GB) DDR3-1600 Memory ($62.99 @ Newegg) Storage: Samsung 840 EVO 120GB 2.5" Solid State Disk ($97.99 @ Mac Mall) Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive ($59.98 @ OutletPC) Video Card: EVGA GeForce GTX 760 2GB Video Card ($249.95 @ Amazon) Case: NZXT Source 210 (White) ATX Mid Tower Case ($45.98 @ Newegg) Power Supply: Rosewill Hive 650W 80+ Bronze Certified Semi-Modular ATX Power Supply ($69.99 @ Amazon) Total: $801.86 (Prices include shipping, taxes, and discounts when available.)
