Hey, First I'm pretty sure this is in the right section, But I'm sorry if it isn't.
I am looking at parts for a new system, In terms of graphics I just wanted clarification.. In future I plan on buying something like a Nvidia GeForce 660Ti, But until I can afford that I plan on using on-board graphics with Intel 3570K (overclocked with after-market fan) Looking at benchmarks this seems better (not overclocked) than my current discrete graphics which is ATI Radeon HD 5450...Would I be better not re-using my current graphics and using on-board until I purchase the new card...Or should I continue using my ATI Radeon HD 5450?
Well Tom's lists Intel HD4000 many tiers above the 5450. I don't think you have anything to lose by trying the onboard and if it totally sucks compared to what you were used to with the 5450 you can just drop in the 5450. But if you are happy enough with the onboard, then don't use the 5450.
Yes Intel HD 4000 outperforms the Radeon 5450 but that isn't saying much. It will suffice for games on the lowest settings and you will probably need to play at no higher than a 720p resolution. The 5450 is more for HTPCs and HD video playback, it is not a gaming card. Use your integrated GPU (Intel HD 4000) until you can afford a new discrete GPU.
ASRock can be great. They had rough beginnings a few years back, but some of their current boards are top-notch. For example, their Z77 Extreme 4 is one of the most recommended Z77 boards if not already the most recommended Z77 board.
What's your total budget looking like? What parts have you bought already?
Getting a nice GPU like the 660ti ASAP will enhance performance so much more than getting an SSD. SSD's are great, I can't have a PC without one anymore, especially because I reboot all the time for tuning overclocks in BIOS. But if you're just trying to game then you really need that GPU.
I like the 64GB SSDs because I only use my SSD for Windows, drivers, and a select few programs that benefit from it. Some people will suggest a larger one so you can put games on it. I don't notice any added benefit to having games on my SSD. I have a 128GB now with all my Origin games on the SSD (BF3, Crysis2, Crysis3 Beta) and I don't notice any difference than when I had them installed on my 7200RPM HDD.
An SSD is nice to have and it's overall simpler if you get the SSD now before you install your OS and all that. Pretty much any SSD will speed up your boot and update times vs a HDD, which for many people becomes worth it. In gaming you won't notice any difference in fps, but level-loads will be faster in most games.
But when considering gaming performance - stickg1 is right about you needing the graphics card since integrated is so limiting. I guess since you're used to a 5450, you should be able to grit it out until you can afford a good discrete card. But like I said - the SSD won't really do much for gaming aside from shorter load times.
As far as recommendations for SSDs, the M4 is known for great reliability. The Samsung 830 is excellent as well and would probably be what I'd be looking for. If you can squeeze it, a 120gb of the same version SSD will be faster than a 60gb and you'll obviously have more space. But again, for gaming specifically, the GPU should be your priority.
